4. Take care of yourself.

You can't be your best at work if your body and mind aren't tuned up and ready to go.

This tune-up includes exercise, eating foods that give you steady energy, sleeping enough, making time for doing the things that you love, and taking care of basic responsibilities (like paying bills and getting your annual physicals).

They're boring, sure, but neglect just one of them and you'll notice that you are not as clear-headed, energetic, or creative. What elements of your own self-maintenance do you need to pay more attention to?

5. Define your personal brand.

You have certain characteristics that really make you shine: maybe you're creative, or judiciously fair, or keenly analytical, or generous. Which are yours? How often do you live up to the "best version" of yourself?

Imagine what daily life would be like if you remembered who you really are and you held yourself accountable for being that person. Those character traits will catapult you forward in your career. Try making a list of your superpowers and reading them each morning, and see what a difference it makes.
