6. You consider your future with worry and fear.
There's only so much rent space between your ears. Unhappy people fill their thoughts with what could go wrong versus what might go right.
Happy people take on a healthy dose of delusion and allow themselves to daydream about what they'd like to have life unfold for them. Unhappy people fill that head space with constant worry and fear.
Happy people experience fear and worry, but make an important distinction between feeling it and living it. When fear or worry crosses a happy person's mind, they'll ask themselves if there's an action they can be taken to prevent their fear or worry from happening (there's responsibility again) and they take it. If not, they realize they're spinning in fear and they lay it down.
