I think the key point here is that Steve didn't start writing because he wanted to make a ton of money. For him, writing is an outlet -- a way to express himself. That's similar to music, art, or athletics for other people.
I get that, since my outlet of choice is writing, too -- and I've managed to jumpstart my blog's success that way. But my blog isn't a way to make a huge income. I have urges to write. I get all itchy when I haven't written for a while.
Today I had this huge to-do list of other things to do, but when I started reading some blogs this morning, I got an insatiable urge to write. I hadn't written in 2 weeks, but three hours after I got the itch I finished a groundbreaking post called "You Are Worth More Than You Think: Overcoming One of the Top Reasons Entrepreneurs Fail." (It will be up at
erica.biz - Erica Douglass challenges you to change your life! tomorrow.)
Writers write because they can't NOT write. I go nuts if I don't write. I've learned to channel that itch into something that helps other people instead of making it all about myself. I can see a lot of similarities in Steve.
Don't think it's about the money. Don't force yourself into "blogging" or "writing" because you think that's what will make you a lot of money. Do something that you'd do even if no one ever paid for it.
