I'm sure most of you have taken a plane before. And you've probably paid for that flight.Sometimes you time it right and book during a seat sale.

Even though the result was the same our investment in that trip was totally different.And this is very similar to the experiences many people have when they work out in the gym.Some people plan ahead and have a purpose in mind and get tremendous results from their efforts in the gym.Others do not plan anything out and are not sure of their purpose.
