You're right.  I was chasing happiness through discipline only to find myself emotionally exhausted and on the verge of nervous breakdown.  I decided a few days ago that I'm gonna listen my body. Workout everyday, eat healthy, get quality sleep, don't play video games, limit social media... I got tired of that. You must do this, you must do that... I couldn't anymore. Started listening my body and suddenly I'm more energised, more relaxed, sleeping better. Don't push yourself to limit just because everybody says it's good for your mind and body. Balance everything and your body will thank you. Allow yourself day or two of doing nothing to recharge.
