How can I become more ambitious?

You should try to do new things. What is something you have never done? take pottery or cooking or dance classes? Go to a pet convention, other convention, paint a picture with your eyes closed, tie dye some shirts, bake a cake from scratch, open up a cook book with your eyes closed, point at a random recipe, cook whatever it is. read more books and magazines, make a collage, make a decoupage. Photograph the alphabet. "find things that look like letters but are not, don't move them around to do it, like a tree might look like a V, " make a slam book.
