Chas.... the only thing dumb about a fifth grader would be the expectation that a few days after he got a drum kit for Christmas he would be able to play it well enough to make decent time and music...
Oh, hold on, that's not a fifth grader! Fifth grader don't CARE that he can't play well yet. He just wants to make some NOISE! It's only old guys that are dumb enough to think they OUGHT to be able to play well after only a couple of days on it
So I guess you ARE dumber than that fifth grader. Only not for the reason you think!
Ask any kid playing the drums how many YEARS it took him to get there (if he's playing semi-decently), and then cut yourself at LEAST that slack. The hell with experience on something else..! Kids learn FASTER than adults, and WAY faster than senior citizens
And even though it takes them YEARS to get good, they don't complain if it doesn't come immediately. That's because they are having too much FUN..!
Just have fun, my friend. It'll come. Just be realistic...
You know - like a fifth grader.
