Embrace that there are many things you don't know. Focus on your strengths. Help something without their knowledge. Teach others. Waste no time with naysayers. Skip email for a day. Take time for you.
Surround yourself with smart people. Quality not quantity. Collaborate often. Remove negative people from your life. Have a flexible strategy. Avoid playing favorites. Leave politics to politicians.
Adopt an open-mind policy. Be true to you. Be clear on your beliefs. Let your team take credit. Surround yourself with people who improve you. Say thank-you often.
Don't compare yourself to others. Clearly define your boundaries. Believe in you. Do what you say you will do. Recognize the efforts of everyone on your team.
Never stop learning.
