It's easy to get caught up in the details--so many hours per day, income and blogging and social networks and e-mails.
I could spend hours every day working out blog posts or visiting other sites. My main reason for this isn't the income (although that's necessary or the "dream" will come to a halt) but to write.
Everything else is a sideline. It's hard to remember that, sometimes, when I read about online publishing and the requirement of having a "following" in order to get published. That leads to discouragement and other less interesting things, and I find myself doing things rather than writing.
More than just writing, I want to write well and to write things that people want to read.
So lesson 7 would be, remember the why. Remember why you're chasing your dream, and don't let the sidelines interrupt.
