Well, to answer your question, not much.

3 out of 4 days Im home around 530. I skateboarding or play basketball with friends for about an hour, eat dinner around 7.

Ill then get down to writing code til around 10, then troll blogs/yc for 15 minutes, shower and end up hitting the sack around 10:30 - 10:45.

Then there is pillow talk with my gf, which probably the pinnacle of my 'social life'. Then Ive got the weekends to hang with friends and stuff.

Does that satisfy your curiousity?

Thanks for the response. I wasn't curious for specifics, I was thinking about the tradeoff between productive and being social in general. That by optimizing your hours for productivity you might lose out on a lot of other stuff.

Glad it works out for you.

Social life starts way before 10PM. Not everything social is a late-night party.

You miss out on parties, but that's not all. Because sleeping just after dinner is unhealthy (it becomes the equivalent of the late night snack) you also have to move dinner forward to something like 5pm or 6pm. Result - you won't be able to eat with friends anymore.

When you go to bed at 10pm you don't just trade a few night hours for morning hours, your entire schedule has to shift. Don't think that's worth it.

No one has to eat the early-bird special because they get a good night's sleep. Listen to your individual body, not the generalized recommendations of others.

A normal 10pm bedtime does not preclude late nights now and then, anyhow.
