For me, it's a combination of things.
Having a close circle is part of what makes me feel good. My immediate friends, lover, and my sisters/mom/dad.
Me doing anything I want and not having worry about approval has also brought me a ton of happiness. I didn't know WTF freedom was until I had to depend 100% on myself.
Little things like food
, my dog, automobiles, music.
I feel like all of these things add into a pie and when I have them all, the pie is complete. And I feel good.
I used to think Happiness was sorta like a 'high', that would last forever. But I'm starting to see now it comes and goes, and during those moments I don't feel like I'm on a high, I'm not sad -- I'm just content. But my spirit is happy. And that's pretty much how I've always been.
I couldn't imagine being an unhappy person, or miserable. The few times I ever felt like that, I literally felt like death was the only option. But that was when I was younger and everything felt like it was the end.
I'm really just happy to be on this Earth and experiencing all it has to offer.
