A rolling snowball gathers no trees, until it gets really big

I've come to enjoy writing more because it's something I can change in the most minute manner, which is funny because I always enjoyed acting as something I would do, it would be done and that would be that. But I really like the amount of control I have, I can completely erase an entire paragraph if it isn't going the way I like, or I can add a single comma to ever so slightly accentuate a pause. I also like the fact that sometimes I have an idea which becomes a sentence and just starts rolling like a snowball picking up snow, and sometimes I have an idea which I think is interesting but it never really goes anywhere...
