no. I wish I loved drawing like that! I'm a pretty good artist but I can never just get myself to buckle down and draw. I keep telling myself I should draw more, but then I'm just too lazy to get the supplies out or I can't find something to draw. But when I do draw it's fun, it just gets boring for me after a while. Anyway, you'll get really good at the rate you're drawing, practice makes perfect! And of course there is nothing wrong with it, it's awesome if it's something you enjoy and it's not getting in the way of other responsibilities and relationships :)
If you're asking if there's something wrong, no, unless it is interfering with everyday life. You can't pay your bills, work, date etc. then maybe you're obsessed. But if you're just drawing when you have free time, or you're making time to do it. How do you think the greatest artist through time achieved greatness? They didn't wake up 1 morning & decide, hmm I think I'll be a Grand Master, maybe oil, or sculpture even. Read their stories, they had what we "normal-ha ha" people call nutty fanatical obsession. When you're showing your work, drop me a line
It's not a bad thing to be passionate about something like drawing. However, it can become a bad obsession/hobby if it begins to ruin plans, relationships, and so on. But if it doesn't interfere with everyday responsibilities and normal life then you're good!
No. If that's what makes you happy and you're passionate about it then go for it. Who knows, you might be able to build a career with that. Now imagine getting paid for doing stuff that you really love, how cool is that? :) I love drawing too and I don't consider it as a job. XD
