To be a great leader, you need to start by leading yourself

• Think of someone you thought was a bad leader and list any of the negative behaviors they displayed.
• Ask yourself if you share any of those behaviors — score 1 for not likely to 5 for very likely: for instance, someone who kept important information away from employees, a micromanager, a vague communicator, a yeller, someone who didn't keep their word.
• After you identify your potential areas of improvement, make a plan for how you'll work on them.

Every day, take 5 minutes to think about the challenges you've recently handled and the ones that you'll still need to manage.

Ask yourself how your leadership failed yesterday. How should you have faced those challenges? What about your challenges today? What would you do differently?

Regardless of how well you are prepared for a situation, there will always be people who will frustrate or anger you.

When those situations arise, first ask yourself, on a scale of 1 to 10, how important the issue is at the moment. With anything less than a 6, take a break and ask yourself how a leader you aspire to be would handle this situation.
