I was drinking too much of it, it became a problem - tolerance, withdrawal, messed up sleep cycles. Also I've read that it stresses adrenal glands and may cause cortisol issues.
Bottomline is - I want a sustainable lifestyle, and with coffee it became unsustainable.
This year I've learned that to achieve my goals I have to learn to think long term, treat it as a marathon, not a sprint. From a big picture point of view, steady, measured, consistent pace is better than short term highs followed by inevitable lows.
2. Keep up the habits I have finally developed:
- Clean diet - staying away from bad food, coffee, nootropics.
- Exercise - running every day.
- Coding every day - learning from courses or adding features to my projects.
- Writing every day - working on blog posts, video scripts, or at least writing quora answers.
- Writing at least 4 jokes per day. Striving to post them regularly (tweet, use them in my articles, write routines).
- Info diet - reading, staying away from reddit, consuming news only through RSS and HN.
That's pretty much it. I want to stay healthy, make money, and get better at my craft. Nothing else needed.
