Everyone likes to be right and to see their ideas put into practice but sometimes your ideas are not the best it. If, as a leader you are more focused on proving you're right and winning every argument people around you will acquiesce.  You will have a solution but it won't necessarily be the best solution.

This is tough, because it means you have to give up control. If you've hired the right people they will have good opinions about projects and about the way the company is run, so you need to be prepared to listen and let others win. 

When multiple viable solutions are proposed to a problem choose the one suggested by a passionate team member. Why? If it's their idea they're will work to ensure it is implemented properly and it sends a strong message that you are serious about finding the best alternatives.

If you want to find the best solutions to every problem my advice is to sit back and listen to others.
