Foresight

Life is constantly casting arrows in your direction, and the secret to finding happiness during your stay on Earth is by dodging as many of those arrows as humanly possible.  Furthermore, the key to dodging said arrows is to detect them as far in advance as feasible in order that you can then scheme and take appropriate evasive actions sans a hurried, nervous, mistake-prone state of mind.  This mystical quality is otherwise known as foresight, not to be confused with intelligence.
