Changing your mind should be celebrated. People call each other out over past contradictory statements like it's a big gotcha or a sign of hypocrisy and fraud. Maybe sometimes, but much more often it's a sign of growth, humility, and willingness to learn and integrate new info.
If you don’t have value, learn.
If you have value, but nobody can see it, build.
If you have value, and a crowd starving for more, sell.
Learn, build, and sell until you create the freedom that makes you unemployable.
