Are you a fanatic?, have you ever met a highly successful person who wasn't "gung ho" about what he was doing with his life?. Nothing significant was ever accomplished by a realistic person. For many years safety first has been the saying of the human race, but it has never been there motto of leaders. A leader must face danger. He must take the risk, the blame and face the brunt of the storm. @Herbert Casson.
Dorthea Brand once said "All that is necessary to break the spell of inertia and frustration is this; act as if it were impossible to fail. An over cautious person Brunswick bridges of opportunity before he gets to them. Most of the people who sit around and wait for the harvest haven't planted anything. The average person doesn't want much and usually gets even less.
Until you give yourself to something great cause, you haven't really begun to fully live. Security is mostly a superstition. It does not exist in nature, nor do the children of men as a whole experience it. Avoiding danger is no safer in the long run than outright exposure. Life is either a darling adventure no nothing.
