What I noticed i was doing was taking shortcuts for the past year so I can work more on my startup. First few years I barely hung out with friends. Big mistake.

Smaller shortcuts, like eating unhealthy to save some time, not showering everyday, shaving, to optimize my working time, was taking a toll on quality of life in the long term. Therefore I said to myself no shortcuts! This drastically increased my quality of life almost instantly as i take my time now to do "normal" things in life without rush. Actually enjoying it.

I also neglected working out and to do things I really like, always thinking I'll get to it once my startups takes off. Since I decided not to work after 6pm, I suddenly have a lot of free time which gave me the possibility to workout without feeling guilty and do other stuff I like.

I think I can further optimize by doing things like you described and will try some of them. Thanks for sharing.
