Some think happiness depends on circumstance others say it's all in your attitude. What do you think?

Yes and no. It's good to be happy in general, but never to force it on yourself. If your best friend dies, just don't try to make yourself happy and cover up your hurt.

Well... It's not good to force yourself to be happy when you're sad. Sometimes it can feel really good to be sad too. But you can choose not to be hurt by things you couldn't influence anyway. Like, I didn't cry for anyone in my family who died because I decided a while ago that's not something I feel sad about. People die, it's part of life. That doesn't mean I'm never sad. There's plenty of things that make me sad but I try to pick my battles... If I can't change it anyway why not just accept it and move on? 🤷

First it's a choice where you choose happy attitudes or look for them.. but to make it work, ya gotta work on making your self laugh. Then to be truly happy ya need inner peace and good character.

You can't choose to be happy. Your body emits endorphins (feel good chemicals) which make you happier. What you CAN do, is do activities that you know makes you feel better. If you have a friend (or friend group) that you don't like, stop hanging out with them and find friends that make you emit endorphins and make you feel happy. Don't force out happiness, it makes you feel worse, and not showing your sadness will make it so then people will not comfort you and make you feel better. Feed your happiness, show your sadness, control your anger, and express your feelings about things that make you feel bad.

You can be positive but that doesn’t mean you’re happy

I think that halliness is something that you create, because you cant just say one day ooof I'm happy! You have to let yourself be happy

I think happiness is your choice. Circumstances are only factors that affect it.
For example, if something bad happened it would be harder for you to be happy, but not impossible for you to choose to be happy instead of sad.

idk bcuz i haven't really happiness in a while but i assume no.

Happiness comes from within. You don't need a reason to be happy. You need a reason to be sad. Your circumstances do not define your feelings. You decide your feeling, regardless of the situation.
