Today's blog post by Seth Godin is spot on...
Slow and steady
The hard part is "steady."
Anyone can go slow. It takes a special kind of commitment to do it steadily, drip after drip, until you get to where you're going.
You can do it. You just have to keep your eye on your goal, with a firm commitment to reach it no matter what it takes, and then keep plugging along step by step, celebrating those little milestones along the way. Don't give up. Just keep going; you'll get there. :)
