Things to Start Doing
Start indulging in meaningful challenges.
What a true blessing it is that there is always work to be done. Because the real value of any accomplishment is not in the end result, it is in the process of accomplishment.
Success is a state of mind, and the most reliable way to reach that state is by working mindfully through a meaningful challenge. Such a challenge might seem somewhat overwhelming when you first encounter it, yet as you progress through it, you transform the work from overwhelming to fulfilling.
