Don't be caught up in the power and prestige of your position. Nothing is beneath a true leader. You must always be willing to help your team and teammates, even in what may seem to be the most mundane tasks.
Remember that you and your fellow co-workers will occasionally make mistakes. You know that, and they know that. If you have an arrogant attitude, you can expect no help from your fellow teammates in preventing or correcting your errors or theirs.
To be vain of one's rank or place, is to show that one is below it.
