Why dont we become the happiest person?

That’s life. We can’t always be happy.we can accept the life situation that comes our way. Hope and always think positively.

Life is about balance. I've read an article online it clearly made me realize that it's not the situation the real problem. It's how the way we perceive the situation and how we react to it. Basically thoughts turns into emotions, if just witnessing the thoughts without putting negative meanings to it then highly likely you would live a better life.

Well I may not be the happiest person, but I keep a positive attitude in everything I do, and that's better than nothing !

Nobody can be happy all the time. That would be unnatural. And to be the *happiest* person all the time is not possible. Being content with your life is a good thing and it's possible to reach this state of mind.
