You may be disappointed if you fail, but you are doomed if you don't try. - Beverly Sills

At least "try" and give it your best. Drumming is difficult at times but don't sit around wishing that you could play like this person or that person. You "can" in fact do it, just like them. Simply give it your best shot... then, if you fail, you may have some disappointment, but you go on to try again. If you don't try at all, you are doomed from the start.
