Not sure if this counts as a dev skill but

Not needing sleep anymore.

Imagine how much time you had if you didn't need to waste several hours a day just sleeping

I'd love this. This would be awesome!

It would be cool if I still could sleep if I wanted but didn't need to :3

great lines

Agreed! I think about this everyday.
There are some practices I do everyday, just so I can reduce my sleep quote.
Not forcing anything, just decreasing the sleep my body requires.
Like eating fresh and raw food more often such as fruits

That would be great. Just imagine working your 8 hours while others sleep and then being able to hang out with friends and study during the day. You'd be a fucking genius, probably be able to earn a lot more money (more time to work if you so desire) and would be able to enjoy 1/3 more of life.
