My personal experience. There was a time in my life when the idea of having "free time" was a foreign concept to me. I took 12-14 credits in college, worked 60 hours (mostly graveyard shift), plus I had small online side projects (needed fair bit of time) which was making me $500/month and I was fairly busy socially and had a girlfriend. The commute to my work and to my school were both about 1 hour each (NYC subway) and most of time I would sleep in the train to make up for rest and would sometimes miss my stop. I did this for about 2.5 years (give or take). Life was bit of a blur, so much was happening, so fast, it was hard to keep track of everything. But I LOVED it. I loved the rush, I loved having something to do all the time. I loved looking forward to vacation times dates or whatever leisure time I could squeeze in. Now that I am older and have much more free time in my life, I am not even 1/10th as productive as I used to be. Honestly given the choice I would gladly take a extremely busy life over all the free time I have right now. Trust me I am not just sitting around with the all the free time I have. I try to take on projects, learn new things, take on difficult physical challenges (training for marathon), but its just not the same.
