Your IM Practices?

I am about to go heavy into Internet Marketing/Monetization, and I am wondering if the majority of members here go full-time or part-time only? It's not easy to spend 12 hours/day in front of the computer, but I'm sure more success could be had that way. Regardless of your current/past practices, do you plan on continuing them into the future?
CIP - How much time do you spend in IM daily, and do you see your efforts as absolutely beneficial?

I spend up to 14 hours with the computer. It's my job, it's my hobby and people around me bring their computer to repair.

And the problem with programming is that you can loose completly the time.
