Please note though you can train yourself to sleep only 4 hours a day, it doesn't mean you must. What I mean to say is, rest is essential to any long term productive endeavor. I think athletes and gym freaks can attest to this. How much you rest and how quickly recover from stress can decide how productive while you are awake. And probably affects your larger health situation on the longer run too.

>>but was it worth it? I'm not sure.

I won't comment on your habits and whats important to you. But speaking objectively. I would say its bad use of time.

If you are in need of entertainment, which demands a lot of engaging activity I would advice you start to learn playing a music instrument. Again not risking your health in the course of it, but music is a liberating experience. Especially if you learn how to play yourself. It can be very joyful.

And its generally a good skill to have and a lot better than fighting for internet points.
