Happiness increases when given to others.

Projection:

We usually expect others to give happiness to
us. We rarely ever think of giving happiness to others. We don't usually get
what we expect because the other person is also expecting the same from
us.

Solution:

Whatever the kind of person we only have to make
sure that we continue to give happiness to others without any expectations. For
this we have to increase our own treasure of happiness by continuing to be happy
under all circumstances.
