Ask HN: How to hack myself to increase my work hour?

Thank you everyone for your contributions. I've spotted and upvoted some very good answers. If anyone has more tips and tricks please chime in.

Some takeaways so far:

  - work schedule: do 1.5-2h blocks of work alternated by 0.5-1h blocks of non-stress activities, OR blocks of different types of work.
  - eat healthy
  - get enough sleep 
  - exercise
  - meditate
  - alternate sit/stand posture 

Also, since a lot of you are asking, I thought I'd provide more context. I'm the founder of my current startup. My background is software engineering. Love what I do, love my team. I do prioritize my tasks. "Hacking"-wise, I've been doing meditation, eating very healthy (organic, lo-carb, no-caffeine, no-drug), exercising. I can usually bump to 60hrs if I do what I'm experienced with, but things seem to come to a limit of 45hrs under stressful periods.

Thanks to your answers, I now have some ideas of what to fix:

  - sleep: my total sleep hours is fine, but my sleep schedule is wild.
  - work schedule: gonna try balancing the work blocks with relax blocks. I usually get stuck on the computer coding for 3 hours straight. Will have to learn to leave it after 1.5-2h.

So far so good, thanks everyone! Remember to chime in if you have anything else to add.

Awesome answer, Amogha_IO. Upvoted. I will try your work schedule. Thanks a whole bunch.
