Sadness, Frustration, Anger, Depression, and other such sufferings are predominantly (most of the time) caused by the Judgmental attitude or behavior. The above pains could be because of either the sufferer's attitude or because of the attitude of the people related to the sufferer. As an adult we always make judgments; often about others, sometimes about the situation, and occasionally/rarely about us.
It is this judgmental attitude that make us suffer the emotional pain, and therefore make us unhappy. The answer to the question, that why young children are generally happy lies in the lesser exercise of this attitude. (Well, this point could be very much argued, but I am speaking from a general view point).
So, do I mean to say that one should give away the judgmental attitude to be happy - Not necessarily. However, if you are wondering for a solution, then follow this:
When you are making judgments about others, try to put yourself in their place; and when you are making a judgment about yourself, try to put someone else in your place.And if you are unable to do the above, try to avoid the process of judgment, as you may be dealing with a situation, which might be of no concern to you.
The above solution might look simple and obvious. But for an ordinary soul, like me, it is really difficult, and you need lots of practice, patience and persistence to develop the above skill - a skill that will make you a better soul - a better human being, and if you are interested in spirituality it will lead towards the path of self-realization.
