Just my two cents here...
For the past 2-3 years my life has become increasingly hectic. It started out with me having almost too much free time, but now I'm deep into the spring semester with 4 classes, doing a bunch of odd-jobs for money, balancing family obligations, dealing with chores, chopping firewood through the winter, running a few meetings for the local boy scouts, etc... I can list more, but you get the point. All that said I do still have a fair amount of free time, so don't see me as some tragically overworked person-- I'm really not, just busy during the week.
Anyway, even though my situation is not anywhere near as bad as other people (I still have time to relax), I have started noticing that even though there is a definite edge to my daily mindset, in terms of stress, I kind of enjoy being busy. It is almost like a personal challenge for me every morning, and I want to prove to myself that I can make it through the day, and do it well.
In my opinion, it makes the spare moments so much more worthwhile. Things I do that add some sugar to the medicine include: Meeting a couple friends for lunch (really keeps me sane), Just sitting and listening to my favorite music between classes, Playing CSGO a bit too late into the night with some online friends, strumming my guitar even though I suck, when I'm working alone or without the need to talk I either listen to some podcasts or sing to myself (lame I know), spend a little time with my younger siblings (not relaxing at all, but important to do), reading books before I go to sleep, and bear with me here but sometimes I like to just watch people and try to deduce who they are and what they do.
Not entirely sure what my main point here is, but overall what I'm shooting for is this: Look at the little things that spice up your day, and savor the feeling of working hard to reach them. Of course, if you are unhappy in your situation and you don't think that can change, then by all means seek a new way of living. Just don't forget how to live.
