Joan Westenberg suggests giving yourself 5-year timeframes. I love this. It gives you enough time to work on something, even tear it down, and start again.
Why 5 years? Because it’s the perfect amount of time to marinate in the quiet dread of potential failure, without fully descending into the loud panic of inevitable failure. Five years is enough time to tenderize the soul. You could go from a nobody to a legend, or from a nobody to a nobody with five years of extremely detailed regrets. Either way, you’re richer for the experience.
