I'll be in the same boat next month... taking time off for paternity purposes.

While you're off work, you should do things to better yourself, man. Read books, read self-improvement stuff, philosophy, home improvement stuff, jog in the sun and show off in front of sexy chicks in their little summer dresses, learn to cook good meals and stop being afraid to go in the kitchen (good cooking pulls in tons of pussy. I used to feed and fuck so many girls when I was younger). Don't be a shlub while you're not working.
