As for being square socially, I don't talk about art unless it is with another artist or someone important to me. I find it dull to talk art with someone who doesn't understand or care for the creative world. To me they are the square not me. Most people I don't talk art with talk about shallow things that bore me. Not even the news, they just talk about realtionships dating or some tv show that has nothing but sex in it.
Most creative minded people are willing to dig deeper into a plot line of a movie or the meaning of an image, and I find those talks stimulating. Luckily I am sarrounded by philosophers, writers, crafters and photographers. So I have plenty of people to talk to, lol.
As for being round, I am on such a strict diet and run around so much doing errands or standing and walking down the hall at work that even if i sit for one entire day I still lose weight...
We have a sort of hippy all organic natural diet, cuz my partner works at a health food store and with her discount we can aford the healthy food.
Exercise is great but hard to keep up with, I have seen the most results from changing my diet.
