I think what I would say to my younger self and probably to younger just starting-out writers is that a lot of times you're just afraid to put yourself out there and it's uncomfortable because it's working up the courage to do something to push yourself to do those things.
You can forgive people who do not follow you through a philosophical disquisition but to find your wife laughing when you had tears in your eyes or staring when you were in a fit of laughter would go some way towards a dissolution of the marriage.
