5. You strive to control your life.
There's a difference between control and striving to achieve our goals. Happy people take steps daily to achieve their goals, but realize in the end, there's very little control over what life throws their way.
Unhappy people tend to micromanage in effort to control all outcomes and fall apart in dramatic display when life throws a wrench in their plan. Happy people can be just as focused, yet still have the ability to go with the flow and not melt down when life delivers a curve-ball.
The key here is to be goal-oriented and focused, but allow room for letting sh*t happen without falling apart when the best laid plans go awry- because they will. Going with the flow is what happy people have as plan B.
