What things to do in your free-time to change your life for the better?

Work on yourself most of all, you might think focusing on the external makes things better, but in the long-run you have to maintain yourself or else you’ll be too damn burnt out to do anything fun later, saying this from experience, pamper yourself, work out, stare in the mirror and pop every last zit, take care of you before you even think of taking on the problems of someone else.
