Tomorrow is the birthday of one of the coolest guys who ever lived, L. Ron Hubbard. He was highly accomplished in several fields; including as a mariner, a writer and an explorer.
However, for me the area where his accomplishments mean the most is the area of the spirit. He made discoveries about the human spirit and then developed methods for spiritual improvement that anyone can use.
I personally have benefited from these discoveries and techniques to a massive degree.
Here are examples from others of their gains:
