"Fear is the lengthened shadow of ignorance."
--Arnold Glasow
Motivating yourself to act is more about alleviating your fear than it is about provoking desire. Fear of loss is a greater motivator than the desire to gain.
People are filled with desire. Who doesn't have a dream or two? Rare is the person who looks at their life and has no aspirations, no "one day" goal, no moment on a lazy Saturday afternoon when they fantasize about the future they see for themselves, their families, and the valuable people in their respective spheres.
Fear keeps the lid on real dreams. Many people go after only their small dreams because then when it comes to the really big ones, they're terrified. They don't know where to begin. There's nothing they can do to put the fear aside, no one who can help them find the trailhead through the dark woods. No one, except themselves.
So, treat your fear for what it is, not enough information and not enough action to confront it. Do your due diligence and learn all you can about what scares you.
Dare to address your fear and demand that it prove itself better and stronger than your desire to act freely. It remains your option to deal with it, or be dealt by it.
Choose to stay in charge of your behavior, and stay in charge of your life.
This is the Way of Aiki.
