Hope

Hope! Everyone's got some sort of it or the other. It's what keeps us going in life. Life itself wouldn't make sense if there was no hope.
The youngster goes to school with the hope that he/she will be somebody tomorrow. Even if he/she doesn't understands at the moment, his guardians have hope that he will be better with an education.
Businessmen/women are busy making transactions, connections etc all for a better return.
The hardworking farmer works tirelessly with the hope of having a better harvest.
The hardworking young man/woman is assiduously in what he or she does hoping for a better tomorrow.
The government employee works hard at office with the expectation of being compensated at the end of the day.
No one does anything without a positive expectation.
That expectation or optimism is HOPE. It is the fuel of life. Without it, life becomes boring and tiresome. So have it in all you do.
