Shut Up Skills
I got a very lucrative string of shows a few months ago because I knew (occasionally) how to shut up.
The keyboardist that I replaced would talk nonstop to the artist, and it absolutely exhausted her. I know the guy. He’s very likable, and he’s super talented (far more than me).
He lost a great tour because he didn’t have one particular “soft” skill. He couldn’t tell when the person he’s talking to didn’t want to talk anymore.
Never, never, ever underestimate soft skills. Spend time on them. Ask your friends about them. Get a life coach to help you hone them. It could be the only thing keeping you from accomplishing your dreams.
