But if somebody knows how to quantify and track happiness, I'm kind of looking into that as well.
I've seen a few different methods.
My suggestion is to just be happy all the time, and when you notice you aren't happy, start being happy. No need to track it.
Think of it like being thirsty. Your normal "thirst" state is fine, and you do things that keep you quenched (drinking water). Set your normal "happiness" level to fine, and do things that keep you happy (pleasurable and satisfying and meaningful things).
Your default state then is fine, not thirsty (aka happy). When you notice you are thirsty, you drink more. Similarly, when you notice you aren't happy, do more happy making activities.
In that situation, would you track your thirst? Would you say "let me see when I'm thirstier, and track if my thirst levels are improving?" That seems silly to me. Instead, just fix it when you aren't thirsty. Happiness is much the same.
YMMV. :)

I showed that to my wife and she bust out laughing!
She loves that meme, and that one is so applicable. Thanks for sharing! :D
