Promise Yourself
To be so strong that nothing can disturb your peace of mind.
To talk health, happiness and prosperity to every person you meet.
To make all your friends feel that there is something in them.
To look at the sunny side of everything and make your optimism come true.
To think only of the best, to work only for the best, and to expect only the best.
To be just as enthusiastic about the success of others as you are about your own.
To forget the mistakes of the past and press on to the greater achievements of the future.
To wear a cheerful countenance at all times and give every living creature you meet a smile.
To give so much time to the improvement of yourself that you have no time to criticize others.
To be too large for worry, too noble for anger, too strong for fear, and too happy to permit the presence of trouble.
— Christian D. Larson, Your Forces and How to Use Them (1912); adopted as The Optimist Creed by Optimist International, 1922
Background and Context
Larson wrote this for the New Thought movement in 1912 — a loose, popular teaching that the mind's state shapes the world's conditions, spread mostly through books and magazines rather than churches. It's built as a pledge, ten lines a reader recites to themselves, and it later got adopted wholesale as a real organization's official creed, which is unusual for something that started as a page in a self-help book.
Interpretation
Read the ten lines and notice who's actually in each one. Half are entirely about you — peace of mind, thinking the best, forgetting the past. The other half are about other people: every person you meet, all your friends, every living creature. That split matters because the "you" lines can't really be checked — there's no test for whether you're "too large for worry" — while the "others" lines are things a bystander could catch you failing at, like the line about wearing a cheerful countenance and giving a smile.
So the creed's real content is on the outward half, and it's other people who end up grading it. Read that way, the interior lines aren't a separate set of goals — they're what has to be true about you for the outward performance to hold up without becoming a lie. You need an unshakeable peace of mind because you've promised to be cheerful at everyone, always, with no end date. The creed is honest about the cost, even if it never says so directly.
Current Relevance
This reads like a job description now. Being pleasant to every customer regardless of your actual day is a real condition of employment across hospitality, retail, healthcare, and call centers, and it's graded — by a manager, or increasingly by a stranger's one-question survey score that lands in a personnel file. Larson wrote a private, voluntary pledge for people who'd bought his book. A century later the same expectation is a job requirement for people who never chose it, and none of Larson's supporting half — the lines about being too large for worry, too noble for anger — comes bundled with the job. The demand got imported; the internal engineering that was supposed to make it sustainable got left behind, which is a fair description of why service work built this way is exhausting.
Impact and Legacy
In 1922, Optimist International adopted this as its official creed, and that's the reason it survived. Most aphorisms just get quoted; this one got institutionalized — recited at meetings, printed on materials, behind a century of clubs. Worth noting: Larson's original ran twelve lines, and the two that got dropped were the most doctrinally explicit ones, about proclaiming your own worth and trusting that the universe is on your side. What got kept was the conduct; what got cut was the metaphysics. A civic club could ask members of any faith to recite the ten behavioral lines. It couldn't ask them to affirm the cosmology.
Contrasting Views or Controversies
The sharpest objection comes from the sociologist Arlie Hochschild, who coined the term "emotional labor" for exactly this kind of work — being required to produce a feeling, not just a performance of one, as part of a job. Her research on flight attendants argued that manufacturing the required emotion on demand, for years, damages a person's ability to use their own feelings as honest signals about their own life. The creed, read as a lifelong performance requirement, is a self-imposed version of that same demand.
A separate objection cuts against the interior lines directly: worry, grief, and anger exist to tell you something has gone wrong. A person who's fully succeeded at "nothing can disturb your peace of mind" has disabled that alarm system, and the creed offers nothing in its place.
The strongest case against this whole reading, though, is that it may not be what Larson meant at all. Within New Thought's own doctrine, the outward lines aren't the point — they're the technique. You talk health and prosperity to everyone you meet because saying it aloud is how the belief gets installed in you, the speaker, and the listener's benefit is beside the point. On that account the direction runs backwards from how this section has read it, and the creed is exactly the interior-focused document it's always been filed as. That's likely the better account of Larson's actual intent. What survived him wasn't his intent, though — it was the instructions a service club could actually use.
Practical Application
- If you recite this yourself: notice which half you're actually doing. The outward five cost nothing today — a smile doesn't require a good week — which is exactly why they're easy to perform for years while nothing underneath changes. Ask what refilled the interior half, not just whether you kept smiling.
- If you're grading someone's attitude at work: be honest that you can only measure the display, not the disposition, however the review form is worded — and be honest about whether there's ever a real break from "at all times."
- If your group recites a creed together: know what the recitation is actually for. It marks who belongs and rehearses a shared commitment, which is real and valuable — but it also means the text stops being something people can openly disagree with.
Background on the Author
Christian D. Larson (1874–1954 or 1962; sources disagree) was an American New Thought writer, lecturer, and magazine publisher. He trained for the Unitarian ministry at Meadville Seminary — a tradition committed to never requiring anyone to recite a fixed creed — then left in his early twenties for the mental-science movement instead, and never held a pulpit.
That background explains the shape of this text better than its content does. He took the form of collective recitation from a religious tradition built specifically to have none, and built his own version of it. He founded a New Thought temple in Cincinnati in 1901, launched a magazine that reportedly reached hundreds of thousands of readers, and wrote more than twenty books — enough scale and correspondence to know that people who'd walked out of their churches sometimes missed the one thing churches gave them: words to say together.
