The only way you preserve pitching arms is throwing; that makes the arm stronger. There is no way to have a strong arm if you don't throw enough.
(Juan Marichal, Hall of Fame baseball player)
This applies to business also, you can't be any good as an entrepreneur unless you are continually conducting business. Sitting back and thinking about it will not make you any better. Meeting people and making contacts will increase your experience level and make you a better entrepreneur.
