You need to be viewed as a peer by your clients. A peer is someone they see as being on the same level as they are, having gone through many of the same experiences, and can truly appreciate and understand where they are in their life.
If they see you as ‘less than a peer’, they will treat you as an assistant, and an order-taker. They will question any recommendation you make, and likely provide direction to you.
If they see you as ‘more than a peer’, they may become self-conscious and not share things with you. They may enact your recommendations even though they may not understand them or feel comfortable with them.
If you find yourself as ‘less than’ most of your clients, you need to figure out how to rise to their level. If you find yourself ’more than’ them, you need to show yourself as their equal, with your own weaknesses and compassion for theirs.
Or you need to find clients who truly are your peers.
