The essence of happiness, I think, is enthusiasm. To learn, to meet new people, to observe, to reflect. What contributes to happiness is positivity, persistence and giving everyone the benefit of doubt except your own selves. To acknowledge every single person around you for what they've taught you, for the time they've spent with you. To accept that one's viewpoints change with time and nothing is set in stone. To make no claims whatsoever.
I think cynicism keeps one unhappy. How can you be at peace with yourself while busy noticing someone else's imperfections? It's emotionally exhausting.
All the while, it's difficult to be positive when going through a rough patch. If you are being abused or criticized round-the-clock, how will you muster the strength to not displace it to the next person? But that, my friend, is the test. That is where your own personality kicks in. If one is able to keep hope alive while being hit at, she/he in my opinion is an example for humanity. From Prophet Muhammad (PBUH) to Nelson Mandela, humanity survived only due to persistence. Positive perseverance. He swore at me but I 'chose' to smile at him. It was much less exhausting than swearing back and living with the consequences. But what it took was a pause to absorb what had happened and to 'actively' think how to react. Not just react out of an impulse. That's easy and that's why the majority does it. Without giving it any thought.
Keep doing it, it'll take VERY long but one day you'll reap the rewards. You'll smile forever. Contain your tongue when angry and you'll find the secret to the highest levels of bliss.
To happiness!
