Embrace tough assignments. Conventional wisdom suggests that it’s easier to take the path of least resistance by signing up for an easy job, doing it well, and moving on to something bigger. The problem with that theory is that nobody notices when you do an easy job well. It’s far better to challenge yourself by raising your hand for the toughest assignments and work to solve problems that no one else has been able to solve. That’s how you truly become a trusted leader inside an organization.
Never stop learning. Whether you’re an entry level employee fresh out of college or a CEO, you don't know it all. Admitting this is not a sign of weakness. The strongest leaders are those who are lifelong students.
