The point of achievement is not to stop once you get there. Instead, let it set the stage for even more achievement.
With sufficient commitment, whatever you intend is who you are, how you live, and what you accomplish.
Be clear and positive about how far you've come, and relentless about continuing to move in a good and fulfilling direction.
The search for meaning bears fruit when you stop merely searching and start actually doing.
Get yourself clearly and acutely focused on the best possibilities, and fulfill them in the way you live your life.
Rapidly demonstrate to yourself what you're capable of doing. That will naturally encourage you to do even more.
What you expect is, to a large degree, what you get. It's not magic, but based on awareness, feedback, and motivation.
