Optimism

Every individual on face of this earth has positives and negatives, good and bad.
We spend all our life cribbing over all the negatives we possess.

However, we should always look at the positive and try to work on the negatives
One should be proud on oneself, as all the negatives we have can be overcome with bit of hard work and struggle.

This makes us a perfect person. It is only if we can think in those terms during tough times. That is termed as positive thinking.

"Being an optimist does change our attitude towards life. It doesn’t eradicate the tough times. However, it helps us through those times".
