meaning of life, depends on individual experience.... one see failure so feel disappointment..... Other see success so feel happy.... Each and every moment, it gives different experience.....enjoy it....

You learn from disappointments , that's why.

everyone has his own life good or bad depends on person. Life is neutral by it self. Don't ask why the life is so dissapointig, but ask what should I do to make my life better. There is no bad weather, when you dress properly

If you feel that your life is full of dissapointments, ask yourself ' Which things should I learn?

Because of the brevity of earthly happiness. Everything lasts a short time.
