Listen Well - Really listen when someone is talking. Turn off electronics, focus on the discussion at hand and not the things you need to pick up at the grocery store on your way home or start formulating your response. Listen.

Be Curious About Others Ideas - It is human nature to think our own ideas are best, but some great decisions come from collaboration with others.

Ask Good Questions - This shows you're listening, helps clarify items you are unsure of and will help with creative problem solving.  

Encourage Others - Everyone likes words of encouragement. Even if you are the kind of person that doesn't need affirmation remember that others on your team do need those pats on the back.

Be Grateful - Think about yourself, are you more likely to work hard on an issue with some who is thankful for your help and tells you they are thankful or the person who is grumpy and grumbling about every little issue.

Bring Your Ideas and Be Willing to Share Them - Lead by example and share ideas and encourage your team members who are more reserved to share their idea. It might be uncomfortable for them at first, but with practice they will not need to be prompted to participate.
