Well
Here is my advice:
I am a 2nd year full-time college student. I am able to spend alot of time on my MacBook Pro and my other desktop systems, doing stuff for fun. However, I am totally 100 percent disabled at this point. I was in a car accident that left me with a herniated/ruptured disc. I have had two surgerys to correct it, and am on the way to my third here in a few weeks (artificial disc surgery). I have 6 units online, and 9 units in person. I have a pretty busy week, however I do not have a job. School is my 'job', but I don't have an official one, right now. I come home from class, do my homework, and with my time remaining I spend it browsing the web, and doing other misc. things. However, I am not an addictive gamer, but my brother is. I know many people who spend hours and hours and hours gaming and never get anything done. So it really depends on what kind of a person you are.
