I'm a painter

I'm a painter, which is different than being an artist, at least in the way the word artist seems to be understood today. Everybody can be an artist; and any expression, joke or clever idea can be named art if it's at the right place (a gallery, museum or Art Fair). 

Maybe I sound like an old man complaining about what crazy youth does.

But when you work, day by day in the loneliness of your studio, it seems like there a big distance between you and those famous artists that appear at the news.

I think I like to be being just a painter.

Your English is excellent.  I made a couple small changes to the punctuation and suggested alternative words to use.
