The only way to grab the power that someone has over you is to accept your flaws.
Any unaccepted weakness will always be a pressure point and allowing anyone to use it for their own gain will only cause you further pain.
You are a collection of so many pieces that fit into an amazing puzzle. Those pieces are all your qualities and faults, your dreams and fears, your potential and your achievements. They create who you are.
When something is not how you want it to be then you can decide to change it. If something is ok for you then you can decide not to change it. No one else gets to have that power over you.
A flaw may become your future strength. Today’s strength may become a future flaw.
Accept your pieces. Control the decisions about how your pieces fit together and continue to make your own puzzle as unique as you wish.
