There are many jobs that recognize the need for continual updates to your skill sets in an ever improving quest for personal development.
For instance you PRACTICE medicine and you PRACTICE law. You definitely want your doctor to be on top of the latest drugs and methods, and I would hope my lawyer knows of new updates to laws.
What would it be like if we approached every career like this? With the linguistic use of "practice?"
And more so, what if we recognized that we also must "practice" happiness. And love. And kindness.
