I stopped being leftovers about in my mid-thirties. It was the first time I adopted a zero tolerance for yucky feelings coming from others. By the time I was in my forties I had perfected my ability to identify and wipe clean yucky people from my life. I told myself, I can do bad by myself. I do not need or desire to have anyone defining who I am. Period!
I tell young women know who you are and if you don't yet know...wait and pray. Do not fall victim to someone else's trap. Do not allow your psyche to become ensnared in anyone's personification of you. Decide early what people are telling you and what they are not showing you. Especially seek to understand their motivation behind their words and actions. The first time you begin to feel like leftovers...run and don't look back. The pain you may feel by running is nothing compared to the pain that awaited you by remaining in place.
Love yourself hard and unconditionally! Free your mind, your awesome life will follow.
