Eyes on the Prize, Buddy
When you're driving, you (ideally) keep your eyes on the road, right? So when you're creating your career, you should keep your eyes on the goal.

This may sound like a complete contradiction to my post last week, which was about enjoying the journey, instead of focusing on the destination, but the idea of keeping your eyes on the prize is not about waiting for your life to begin; it's about making sure that your choices have your goal in mind.
