What small changes resulted in big improvements in your life?

In the last year I have made two changes:

* regular consistent exercise. Started small 10 mins of running and 10 push-ups. Slowly increasing volume, but never pushing to the point where I’m sore later.

* started cooking for myself. It was a huge paradigm shift going from eating fast food for lunch and dinner to having meals that I can through together in 20 minutes.

Just from these two things I have seen a world of difference in my mood, mental state as well as my physical abilities.

EDIT: quitting FB cut out a lot of noise and the feeling of missing out. Once that was gone I cared less about what people thought I was doing.

No user-generated content (except HN).

Stopped using Facebook, and never started using Twitter, reddit, Instagram, etc.

I don't read comment sections or user-generated content anywhere else. It has been great for my mental health, time, and perspective about the world. I have not felt less informed.

Writing out rules for life and trying to follow them:

Getting an eink secondary monitor for my workstation. I use to get pretty bad eye strain that lasted for days from LCD screens. It got so bad I forgot how it feels to wake up without my eyes hurting. Now it's all gone.

The product offering of eink screens is virtually non-existent, the only usable one for interactive work that I found was the Dasung 13.3", which is the one I got.
