Part of being a leader is giving back. I am not talking about material things, althought that is also important. I am referring to those things that you simply cannot put a value.
Good habits. Accountability. Integrity. Honesty.
The people you lead, will learn from you. They are always observing you. You are on the stage every day even if you are not aware.
If they see you doing good, they will learn.
Lead by example.
You must take time and put in the effort to develop future leaders. This what sets you apart from just being a good leader to being a great leader.
