So will you.
Your setbacks might happen before you have any successes.
It’s likely they will, in fact.
What separates the best from everyone else is THE BEST KEEP GOING.
Learn from the mistakes and move on. Your future best stuff is better than your current best stuff.
If you gave something your all and it doesn’t succeed, maybe you simply learned ways it didn’t work. But some future success may very well depend on having learned that lesson.
