I never had massive amounts of free time at college. Maintaining a 3.9 in Computer Science without having the same amount of raw talent (and previous experience) as your peers is really hard, so I had to work my ass off. My schedule was close to 16 hours per day, 7 days per week (including classes). It was "Hell Week" for the ~4 years I was there. I worried my family and friends. It was unhealthy.
Trying to keep up with, frankly, __smarter__ (and, most likely, more intelligent) peers was a real challenge. I tried "Studying Smarter, not Harder", but lacked the skills from K-12 education to do so. Attending classes on "How to Study" and the like really didn't help and, no matter what I tried, I always fell back into investing more time as a solution.
I lacked the bio-hardware (read: brains) to go into Computer Science. I did it anyway. Don't forget about people like me!

No, it wasn't. Not for me.

I don't. I have more free time now that I'm married and working (a stable and well-paying job, thankfully).
