Gratitude is like love or fresh air - you can't get too much of it.
Surprise your doubts with action.
Why are you afraid? This is where you get it out of your system: bankruptcy, unfulfilled potential, trashing your reputation, losing it all. And then (because we just can't stop there), you're going to apply some simple analysis to it.You may have nothing to fear after all.
If it doesn't light you up, you're not the right person for the job.
If you're making art, you are not separate from your brand.
Decide to get over it. You know, just let it go. It can be that simple.
