How can you have more free time?

I was wondering, how people do things like maintain an artistic hobby, have a busy job, and go to the gym, or have a family and work a busy job (I don't know how my working mother friends do it). It seems like they have a lot more free time than I do, even though I don't do anything.<br><br>I am in college and taking 16 credit hours, and I work 20 hours a week, and I have a long commute to work so I only have like 3 hours of free time during the week. Most of that time is spent scrolling through a screen doing nothing. What do people do to create more time for themselves to do things that are fulfilling?
