FUN FACT: Girls actually will suffer unearthly tragedies and still actually run errands the same day with a smile on their face but if a man's parents divorce when he is 12 he will unleash his wrath on the world for the rest of his life.
Keep your problems smaller than your life. A flat tire is a flat tire. A bad meeting is a bad meeting. A canceled flight is just an extra two hours. These things become catastrophes when you let them.

Fit your reaction to the size of the problem.
