It took discipline for me to get into a workout routine, 4 days a week. Now if I don't do it I get stressed out.
But if I had not pushed through the first two months of exercising those 4 days a week with discipline, I would have high blood pressure, probably be pre-diabetic. Now I have a great BP, blood work is fantastic and I have more energy during the day than ever before.
I had to use discipline and motivation to change what made me happy. Things that are generally good for you are not easy to do. Id rather binge netflix, play video games all night and eat ice cream in my younger days because that me me happy. I was actually just killing myself quicker.
The logic of do what makes you feel good or happy is so flawed. Doing heroine or shooting morphine feels amazing, but that does not make it ok.
