Not every soul is potent of remaining happy all the time. Only a few people who can accept everything that comes along the way can hold this attitude. Thus, happiness is an attitude of mind. Not everyone can remain happy and keep smiling; only a handful of people can do that, which is certainly not a matter of joke.
Often, we get so obsessed about ourselves and the situations around us that difficulties tend to dominate us. A few people are actually determined to be happy. They have the capability to shed off all their stresses and every sadness as well.
They are the kind of people who believe in remaining happy and holding on that smile on their faces. No matter what the situation is, this set of people are the ones who can see the good things beyond all the miseries and challenges.
