H is for Hobbies...

 This post deals with what your characters like to do in their time off, to relax and destress. 

A well rounded character will have a hobby or two to keep them busy during downtime or when they are stressed out to help them relax. 

Any hobby a real time person would have your story character should also be able to have, there are no boundaries, expect that you know enough about them in order to accurately portray them, which may mean for you, hours of research and possibly taking up a new hobby.

Maybe they like to write short stories, or a novel in their spare time. Or maybe they like to knit and crochet, their efforts ending up as gifts (wanted or unwanted), for their hapless friends and family.  

Maybe they like to cook and bake, their produce going to sales of work, or stocking a local food bank. 

They could on the weekends like to go skateboarding, dirt biking or surfing, enjoying the adrenaline rush. That could even be too tame for them, so rock climbing, or free rock climbing, abseiling off bridges or parachuting out of airplanes.

Your character might like to box, practice martial arts, use a bow and arrow, or they might be into DnD, playing a P.S or an Xbox, they might be a couch potato watching TV movies or reading a book, like to go to karaoke bars, or attend dance classes. 

In my own novels the MC of my first novel 'Sorceress' likes to read old novels written by the likes of 'the' Merlin, my Vamp uses her free time to track 'food' (people who are despicable and unredeemable), as well as research where her sire and his Cabal are hiding so that she can take them out. My tall blue Alien with no mouth likes to practice fighting with her bo staff and using her limited telekinetic abilities.

The point is, that in order to have a well rounded character they need to have something they enjoy doing in their spare time. They might be good at it, they might be awful, but at least they have something to keep their minds and bodies going.
