Do you KNOW YOUR VALUE to yourself? Ever write down whom you are as an ingredient list of components?
What would be at the top of the list?
That's the easy part. Here's the hard part.
What is your value to others? How do you know what they tell you is true? Perhaps they don't want to hurt your feelings so they are super kind if not completely honest.
Perhaps they want something from you so they are very complimentary and superduperkind.
How do you know that what you think is your value to them is really what they value in you?
T'is something to ponder upon if you have the inclination to do so. Whatever answers you come up with may or may not be true. That's life.
