Yeah life is always a distraction, sadly enough v.v
Good think you're doing your best to follow your dreams though! Sad or not, your hard work will surely be re-paid with time, so I'd say it's definitely worth it.
If you ever need a chillout though, or break from studying, it's always possible to draw then.
If you find too many options distracting, I'd say try to start with one, then go over to the next. It's better than not doing anything just because you couldn't choose. ^_^
Of course, I compare myself to other peoples art on a daily basis. Not in a bad way though, instead I strive to become better. It motivates me and keeps me myself practicing. I just find it easier to have a set style to offer in my shop, and better that one and improve that one as well as improving other parts of my art in private, which I then could offer in the future instead.
