What's one thing?

What's one thing you were never taught, that you had to figure out the hard way?

Could be money. Could be how to talk to a customer. Could be just showing up when you didn't feel like it.

Drop it below — no wrong answer, no judgment.

I'll go first: nobody taught me how to price a job right for the first 5 years. I gave away more money than I want to admit before I figured it out.

Your turn.
