Happiness requires evenly balancing your multiple nonnegotiable goals, blending in a negotiable goal where appropriate . . . and never, ever forgetting to self-evaluate along the way to ensure the balance never gets out of whack. For brief periods of time it’s okay if that balance is off, but do that for long, and everything falls apart: your motivation, your confidence, your small successes—and ultimately, your happiness. Because success isn’t truly success . . . unless you’re happy.
