my legs, and drop all the fly balls hit to me,” would the coach let you play? More likely, he or she would kick you off the team! When you
pretend that you can’t do anything in physics, you do yourself a tremendous disservice. Pick something that you can figure out, some topic you
can develop confidence in, and go from there.
