"The capacity for getting along with our neighbor depends to a large extent on the capacity for getting along with ourselves. The self-respecting individual will try to be as tolerant of his neighbor's shortcomings as he is of his own."
- Eric Hoffer

From the song 'Greatest Love Of All' by Whitney Houston:

I decided long ago, never to walk in anyone's shadows,
If I fail, if I succeed
At least I'll live as I believe,
No matter what they take from me,
They can't take away my dignity.
Because the greatest love of all is happening to me,
I found the greatest love of all inside of me,
The greatest love of all is easy to achieve,
Learning to love yourself,
It is the greatest love of all.
