I usually sleep 8 hours. I personally know a few people who are extremely sharp, intelligent, fit who sleep 3-4 hours a day. Its genetic or something else. I tried a bunch of things to decraese my sleep need but I wasn't really serious at the time. Now the more time I have the better.

After reading this comment, I wanted to create this post: https://www.reddit.com/r/asktrp/comments/59gjpb/time_is_it_our_most_valuable_asset_how_do_trpers/d98k1w1/

Is there any RP men here who managed to decrease their sleep need? How?
