Dwayne “The Rock” Johnson said something along the lines of this: When you come home from work, you don’t skip working out because you’re tired, you skip working out because you don’t have the right motivation.
So the question is, for any goal that you have, why is that your goal? What is it that you really want? It’s fine to say you want to lose weight, or want to get in shape, or whatever your goal might be, but really ask yourself why that is your goal. What is it that you really want?
If you don’t know your reason, chances are you will not meet your goal, because if you don’t have a reason for the goal, then how will you stay motivated when things get hard? If you really know your motivation, then that will give you the power to get through when things get rough.
