A thousand different things determine the outcome of your life.
Of those thousands of things, you have control over only a handful.
The temptation is to waste energy and effort focusing on things outside your control.
Resisting it takes discipline.
The discipline to identify the handful of things within your control and own them like crazy. To forget about the rest and banish them from your mind. The discipline to live in the present moment undistracted by what’s going on around you.
Discipline keeps you on the path when those thousand different things come calling.
