A lot of "successful" people are tragedies, because what they've accomplished aren't the things they wanted. Intentionally create the question "how" instead of accidentally relenting to the question of "should." If I'm not intentionally choosing a good attitude, I'm almost always unintentionally choosing a negative one.
