I think a lot of people face that same feeling. In the moment a cold shower is terrible. IT is like when you're on the treadmill and you just want to give up. But once you are out of the shower or off the treadmill you're elated that you stuck with it. I think the hardest part is consitently going back to the well to test yourself again, which is why people become complacent and give up on goals and resoluitions. Another thing to think about is that life is all about compounding. You won't see results quickly, but repated healthy habits compound over time and that is when you see results. Awesome post, I know a lot of people will be able to relate to this.
