It's possible that the quote is a variation of a more well-known quote, or perhaps it's a recent invention. However, without any further context or information, it's difficult to trace its origin.
If you're looking for a similar quote with a known source, you might consider these:
* "The best reward for good work is the opportunity to do more." - Unknown
* "The only way to do great work is to love what you do." - Steve Jobs
* "Success is not final, failure is not fatal: it is the courage to continue that counts." - Winston Churchill
It's important to be cautious about accepting unattributed quotes, as they may not have a legitimate origin.
