What is the most critical vitamin to have in your life?
Discipline yourself to live happy, be happy, pursue happy, treat others happily, treat yourself happily, and when in doubt or angst or fed up, get happier.
Happiness honed, cultivated, and practiced, is your ticket.
Your ticket to… happiness.
But like all other highly prized attributes, it has to become a habit.
And habits occur through practice, failure, repetition, and never giving up.
