The only way to keep a strong spirit day by day is to discover who you are in your true nature then make a decision that you will honor that essence by releasing a load of that natural energy everyday to meet that inner standard inside of you.
I wrote A Free Spirit's Search for Enlightenment about how to live the greatest life possible after I discovered the only way I could be happy day after day in the esthetic-euphoric-spiritual-loving sense is to release most of the natural energy inside of me everyday to honor the standard that I was born with.
If I didn't do this, I would feel miserable which is why I have no choice but to constantly keep releasing whatever inspired power lives inside of me. It's the only way to live a great life in harmony with your true nature.
Now that I'm getting older, I find fear creeping in.
