I don't think anybody is always happy but you enjoy moments of happiness and be grateful for them when you're not. I don't think happyness is that one sided either. Those moments that supposedly you don't feel high on life, it's just reflection time and doesn't mean you're not happy.
@leap8 Interesting insight. Thank you for your thoughtful comment. It's all up to the observer, so happiness is just a mental state.
This is an interesting topic that I believe is very misunderstood. not that I understand it lol
I don't it's just "mental". it's when everything that's you is in alignment to its zero point as close as possible. That's what some cultures call "being still" . It's kind of hard to be happy when you just stabbed your toe on the bed and in pain.
