Once you're up and running, keep going. Once you've worked to establish some momentum, make the most of it.
Don't stop when you've done just enough. With a little extra effort, you can achieve so much more.
You've spent a lot of time and effort getting to where you are. If you stop now you'll have to put even more effort into getting started again.
Keep going until you've far surpassed what you expected to do. Surprise and delight yourself with how much more you can get accomplished.
When you've already done what's good enough, that puts you in a great position. It's more effective to reach higher when you're already moving higher.
Momentum is an unstoppable force. Once you've got it, keep using it, and keep going until you're amazed at what you've done.
What separates the ordinary from the extraordinary is that little extra. Find that little extra and be amazed at the results.
