That's everything in life. It's going to take a lot of discipline and self mastery to be good at whatever you decide to do. Anything worth having/doing is going to be difficult. If it was easy we wouldn't have janitors or waiters.
I for one think you should keep them and tackle your dream like a 300 lbs offensive lineman. But if you're convinced that this isn't for you I might be interested in buying that SM58 off of you if the price is right.
No promises, but I "may" be interested.
Donít worry about people stealing an idea. If itís original, you will have to ram it down their throats.
