I can swim, but I dont have the perfect genetic set up of Michael Phelps.

Dont let someone elses abiltity get you down.

Im no Charlie Parker or John Coltrane either.

Keep Practicing. That is the only way to get where you want to go.

If you love doing it, keep doing it. You can't help what someone else is doing, just focus on yourself, getting better every day. No matter what you do in life, there's always going to be someone better, you just can't worry about that stuff.

So...

Did you quit?

You're comparing yourself to someone else, don't do that. It's about how you play, and how you enjoy playing.

You listen to your own music every day, so you don't know what it sounds like when you're playing like someone else hears it. You get used to hearing yourself play and after a whlie that flattens. if you listen to a song 1000x it often becomes boring as well. Don't compare your music to someone elses. Someone else might progress faster, or be better, or give better shows. Don't compare yourself, but learn from others. "What are they doing what I could be doing as well?", "What can I learn from them?"

Whenever you feel like tossing it, or get bored with making music, or whatever, tell yourself the reasons you started making music in the first place. Then start making music again.
