I ate terribly.
I slept poorly.
I did not exercise.
I surrounded myself with people who would put me down regularly.
I was always stressed and I would just sit at home and play video games for hours at a time to avoid things.
Then I started exercising and the whole trajectory of my life changed.
My behavior and habits got significantly better.
I stopped pursuing habits that harmed my personal growth, and I started focusing on habits that improved my lifestyle.
I demanded more for myself and even surrounded myself around people who would lift me up.
This is why I believe that exercise is the ultimate habit builder.
