Do you know what your value is?
This is not a question about how much you should charge or how much your time is worth, this is about how much you value you give to others.
Every service, every product and every role must be able to bring some amount of value in order for someone to want to pay for it or to even spend time listening to what you have to say. Even relationships require a certain value for two people to stay together. I won’t cheapen relationships by calling it a transaction, instead, it is a mutually-beneficial relationship.
