"For nothing should be done without an end in view." -Marcus Aurelius

Imagine having an aim to your life so meaningful and suited to your desires and strengths that every experience feels pointed and purposeful. Imagine being so dedicated to that aim that you know instantly when something isn’t in line with it, and you exit accordingly.

The opposite isn't so hard to imagine either. You regularly find yourself exhausted and unamused; your focus rarely extends beyond that of the immediately gratifying.
