The E-Myth Revisited: Why Most Small Businesses Don’t Work and What to Do About It by Michael Gerber.

Try to not take what they say too seriously. They have (I am guessing) not tried what you have, so don’t have perspective on what it took you to strive for success.

Make note of all your lessons learned, and you would never have learned them had you not tried and failed (someone once told me to fail fast, still trying to master that).

Ask them why they said what they said? And let them know the impact it had on you. Not from a “make then wrong” lens, but from a generous curious one. It may give you both insight.

You have tried and learned so much to take with you on your next attempt, congratulations.
