H.A.L.T. - Never make a decision when you're Hungry, Angry, Lonely or Tired. 

It's typically in those times poor decision making trumps sound decision making. Even Jesus was temped in His wilderness after haven not eaten for several days..... a test many of us would've failed! lol

So, pause a second and allow your self to be put in a position to make a decision you won't regret five minutes later.
