You are very right in what you think, particularly I also believe that happiness is not the same for everyone, what can generate peace for me can generate anxiety for you, for example, I also think that many people think that to be happy they have to be in that state constantly and it is not like that, the rest of the emotions and feelings are also part of being happy, because as you say that's what life is about, living and experiencing small moments. There will be difficult moments, where we are sad or full of anger, but that does not mean that we are not happy people.

I think that's the big mistake people make, that's why many are really UNHAPPY!
