Focus on the controllable

In life we have two categories of events:
those which we can control, and those which we can't control.
Success, they say, involves distinguishing between the two
and directing your energies toward the controllable
while having the discipline to not waste time and energy on that beyond your control

Priorities

Don't tell me where your priorities are.
Show me where you spend your money and I'll tell you what they are.

Scheduling priorities - Stephen Covey
