Pessimism never won any battle

शोकस्थानसहस्राणि
भयस्थानशतानि च ।
दिवसे दिवसे मूढम्
आविशन्ति न पण्डितम् ॥

- महाभारतम्

- हितोपदेशः

A pessimistic ignorant fool is always disturbed by thousands of reasons to cry and hundreds of reasons to be afraid everyday. A wise person is never affected by these.

An optimist sees the opportunity in every difficulty,
whereas a pessimist sees difficulties in every opportunity.
When life gives you a hundred reasons to cry,
show life that you have a thousand reasons to smile.
