One of my favorite sources of insight and inspiration is the ML2 e-newsletter published by Dr. Mark Albion (www.makingalife.com). In the current issue he discusses the reasons we have to struggle to become our unique selves. It's reassuring that to realize, that to some extent, it's natural.
If you are driven to prove your worthiness to others, you have handed over your life to the opinion of others. Cultural dictates are powerful. We each must make our peace with the past and the present, making mistakes along the way, learning from them, if we are going to find our way to becoming an original.
