This is really bad advice...

If you want to get to a certain weight but you just ate two pounds of junkfood or,

if you want to save for a house or appartment but just spend money on something you do not need or,

if you want to get a degree but just did not study all weekend, or

100000 other examples,

and you do not work on yourself and start working towards your goals, you will NOT get to where you want to be.
