Four super important things for aspiring leaders:  

1. Develop an ability to understand what's going on with people around you and stop stressing about being the smartest person in the room.

2. Learn how to see differences with others as opportunities rather than obstacles.

3. Be disciplined about turning down work that doesn't suit your core competencies.

4. Focus on asking for what you want, what makes you happy, what challenges you, and what sets you apart from other people; you'll be able to take ownership of your job and career, and you'll find that you're happier and more successful.
