Hi, @F31! Welcome to Tapastic. : ) It's a nice place, so I'm sure you'll like it here. (also your English is just fine, and nothing to apologise for!)
I'm from Sweden, and I'm a freelance illustrator and comic artist, and I spend most of my spare time drawing my comic Grassblades.
I would like to say "all the time", because it's true. I don't draw when I'm sick, and I do sometimes manage to convince myself to take a day off, but mostly I just draw. I spend a little time hanging around the forums/social media in the morning, catching up on what's happened during the night, but then I start drawing. I draw until lunch, take a lunchbreak, then draw until dinner. Sometimes, I take the night off, and sometimes I go right back to drawing. I can, and will, draw for 12+ hours at a time (getting up regularly and stretching, of course!)
... usually when I'm away from my desk and can't draw. XD I can be in miles away from home, doing something else important, and all of a sudden I get the "aaaah I have to DRAW!"-feeling - and I can't do anything about it!
But in general, I get inspired by other works of fiction - movies, books, other comics, etc., etc. - by historical events (I'm a big history nerd!) and by things people do and say around me.
