I was reading THIS ARTICLE on "My Athletic Life" and came across this quote in an interview:
"Bill Starr said “Success breeds success.” Look for drills and exercises you can do successfully and build on top of them. If I wanted to squat 500 lbs., I wouldn’t load up a bar with 500 lbs. and try to squat it – I’d fail. What I would do is start off with 100 lbs. and build up from there. Don’t just try to do a handstand repeatedly and fail – look for drills that you can do successfully."
There are people that want to jump to the endpoint immediately. If they can't kick up to a handstand in the first couple of tries, or fall off the rings as soon as they try to jump up, they think, "I can't get this, let's do something else."
Most of us have probably been out of school for a while, but if you think back real hard, you probably remember that to eventually get through algebra, you had to learn basic arithmetic first. The same slow build of mental skills translates to physical ones. It's a matter of progressively building upon small steps and introducing your body and brain to new ways of working together.
So step back, take a deep breath, and try again.
