The people who do best with life move beyond the temptation to whine and feel sorry for themselves. They face the disappointment and move beyond it. They acknowledge the bad break and look for a way to turn it around. They work from a half-full rather than half-empty glass mindset.
There is a section in John Baillie's A Diary of Private Prayer that reads . . .
Teach me, O God, so to use all the circumstances of my life today that they may bring forth in me the fruits of holiness rather than the fruits of sin.
Let me use disappointment as material for patience;
Let me use success as material for thankfulness;
Let me use suspense as material for perseverance;
Let me use danger as material for courage;
Let me use reproach as material for longsuffering;
Let me use praise as material for humility;
Let me use pleasures as material for temperance;
Let me use pains as material for endurance.
When a given day begins, countless things are headed your way over which you have no control. It may be bad weather or someone's bad temper, a deadline that won't budge or a client equally resistant to change. The one factor you can control through it all is your attitude toward them.
