Don't measure yourself by what you have accomplished, but by what you should have accomplished with your ability. Do not let what you cannot do interfere with what you can do. Be more concerned with your character than with your reputation. Your character is what you really are while your reputation is merely what others think you are. Failure to prepare is preparing to fail.
John WoodenWe almost have to force or drive ourselves to work hard if we are to reach our potential. If we don't enjoy what we do, we won't be able to push as hard as we need to push for as long as we need to push to achieve our best. However, if we enjoy what we do and if we're enthusiastic about it, we'll do it better and come closer to becoming the best we can be.
