Is there someone who makes you want to do more,
stop doing something,
or just do?
Find these people and spend time with them. Read their blog or book. Watching them on TV. Do what ever puts you in contact with them and feed on the inspiration they give you.
Do it often and keep doing it! Its like putting fuel in your car, or electricity in your wall sockets. We all need a robust stream of energy to keep us going.
