Happiness and outlook may indeed be intertwined.
An outlook may be refined by balancing past, present, and future.
Some people think that happinesss is real only in the present moment.
Nevertheless, a past positive memory brings happiness to the present.
Likewise, a future expectation also brings happiness.
The secret is to avoid spending too much time in the past or the future.
The effect of something unpleasant is lessened by adopting the outlook that everything passes.
Every second is a stepping stone to the next second and so on.
An outlook of learning from both positive and seemingly negative events paves the way to happiness.
