Writing is a lot like sex. Sometimes it's easy, and enjoyable, and better than therapy. Everything flows, and you don't want to stop, can keep going for hours, and it makes you feel good about yourself.

Sometimes it's a struggle, and you're not in the mood, and every little bit of progress is a huge effort. You might need therapy because of it. Things on your mind get in the way, and you feel bad about subjecting other people to it.

Sometimes music helps, and most of the time alcohol is involved.

And the majority of what you'll do in your lifetime probably happens alone.
