The initial going from non-work to work is a very hard transition to make. I remember after I graduated school and went to work and just the realization that there'd be no summers off or real vacations was depressing. It did not help that I worked retail and in the basement of a building and got to work before it was fully light out in winter and left after dusk was well established. It is hard not to focus just on working but if we're working at least 8 hours a day and sleeping 8 there's still 8 hours out there that are our own and that we can do stuff. You have to get an interest/hobby and start following a dream in those hours, get to know yourself better and what you want and learning all the stuff you didn't learn coming up with perhaps not very useful parents, siblings, or friends.
