“ As long as we require someone else to make us happy, we are slaves. ”
Source: The Complete Works of Swami Vivekananda
Stop comparing yourself to other people, just choose to be happy and live your own life.
As a well spent day brings happy sleep, so life well used brings happy death.
If you read someone else's diary, you get what you deserve.
You must learn to be happy here and now, under all conditions.
Happiness lies in making others happy, in forsaking self-interest to bring joy to others.
