Brian Tracy, the expert on human potential, says…
EAT THAT FROG!
What does this mean?
Eat that frog first thing in the morning and get it out of the way.
What is your frog? Working out? Making calls? Studying? Cleaning?
When you do the most difficult thing first, you not only get it out of the way, but you gain confidence and momentum. Otherwise, the frog will be staring at you all day and zap you of your energy.
