I believe this is one of the most important things that you can teach a child. It doesn't matter what they do now or what they grow up to do later. Status and wealth are unimportant. If you can't love yourself then you will never truly be happy with the choices you make.
no matter what you have done or not done, no matter who you are or who you are not, no matter who you become or do not become, you are worthy of love, and dad will always love you no matter what. btw, i repeat this to them regularly. i simply encourage them to be the best "themselves" they can be. we are all masterpieces anyhow.
