What you think is self-awareness may just be self idealism. Just because you think you know HOW you are doesn't mean it's an accurate view. There's a reason we use mirrors (and avoid them!)
If you REALLY want to know how you behave as a leader, boss, or team member, you're going to have to get vulnerable. One of my favorite authors, Brene´ Brown says,
“Vulnerability is the birthplace of innovation, creativity, and change."
If you want to go to a new level of leadership, you're going to have to start asking some tough questions (that you may not want to know the answers to).
If you really want to become more self-aware, sit down with the people you interact with regularly and ask THEM how they see you. Lean in. Truly listen. Give them the opportunity to be truly honest, and use what they tell you to sharpen your skills.
Each individual is a unique blend of traits and gifts, strengths and weaknesses. Discovering your "blend" is work, but it's worthy work. The more you truly understand yourself, the more effective you are at being truly you.
