Your greatest gifts are not the things that we immediately think of. They are things we have that we never even think of. And without your self you could never even be thankful or experience them. The greatest gift we have is our own self. Learning to work in harmony with it will always give successes, working against it will always fail miserably. You were given this gift, so be thankful. You certainly did not create it or decide how you were going to be. You are what you are and you are stuck with it, learn how to use you and to get the best out of you. Yes much of us changes but there is that of our selves which is unchanging, despite the everchangingness! Get in touch with it, accept it, embrace it and go forth with it. This knowledge is an essential part of your health for harmony is itself health.
There will never, ever be another you! Embrace your greatest treasure! Invest in yourself!
