taking some years off

[tommo]

so I am graduating this december and did fairly well in school (3.7 gpa in theoretical math and applied physics, definitely near the top of my class)

I am planning on taking some years off to work on some business ideas. Do some serious investing. and play poker (I'm pretty good at poker).

eventually I think I'd like to come back to academia for math. What sorts of things should I be doing to make coming back to school easier before I graduate? Especially considering I will not have a boss when I leave.
