I agree totally with you about living authentically - by your own values, and not using/allowing externalities to distract you.
Life is both serious and joyful all at the same time. It is interesting - in trying to live my lilfe authentically I have made many 'mistakes' or things I would do differently, but that is all part of the learning.
I feel as if I am on a road I didn't choose to be on, but since I am on it, it is up to me to do the best job I can.
We can spend all our time looking back to what we had, or we can try and enjoy or at least experience fully, the journey. It isn't always fun, but we have to do the best we can for ourselves, and for others.
one thing I have learned is how important friendship is, and I hope I am learning to be a better friend. I have always had friends, and I feel as if they have saved my life.
