Your OP is rather opaque, so hopefully this addresses your question.
I do believe that it is possible to be happy and more than that, to lead a happy life.
But I do think that increasing numbers of people have forgotten what happy means. And it doesn’t mean brimming with joy at every moment.
It doesn’t mean always getting your own way.
It doesn’t mean never being temporarily bored, stressed, annoyed, inconvenienced, upset or offended.
It doesn’t mean having all the material things you’ve ever wanted.
It certainly doesn’t mean being centre of attention all the time.
Happy is having enough: a family you love, friends and community, somewhere safe to live and work to do. It’s having the resilience deal with the “rainy days”.
