I often refer my friends who are hung up on one thing or another, waiting for some kind of clearance or approval, to this quote from L. Ron Hubbard:
The only possible way that you can get any freedom is to stop asking everybody's permission to be.
I first heard that when listening to the Philadelphia Doctorate Course lectures given in the early 1950's by Hubbard. I've listened to them 4 times through over the last 20 years, and I gain something vital and new every time I Iisten to them, from every lecture. My understanding builds over time and with the number of times over the materials. Understanding of what? Of life. Of how to live my own life better.
