[1]An 18-year-old student was struggling to pay his fees. He was an orphan, and not knowing where to turn for money, he came up with a bright idea. He and a friend decided to host a musical concert on campus to raise money for their education.

[2]They reached out to the great pianist Ignacy J. Paderewski. His manager demanded a guaranteed fee of $2000 for the piano recital. A deal was struck and the boys began to work to make the concert a success.

[3]The big day arrived. But unfortunately, they had not managed to sell enough tickets. The total collection was only $1600. Disappointed, they went to Paderewski and explained their plight(困境). They gave him the entire $1600, plus a cheque for the balance(差额) $400. They promised to pay the cheque at the soonest possible.

[4]“No,” said Paderewski. “This is not acceptable.” He tore up the cheque, returned the $1600 and told the two boys: “Here’s the $1600. Please deduct（扣除）whatever expenses you have spent on. Keep the money you need for your fees. And just give me whatever is left”. The boys were surprised, and thanked him a lot.

[5]It was a small act of kindness. But it clearly marked out Paderewski as a great human being.

[6]Why should he help two people he did not even know? We all come across situations like these in our lives. And most of us only think “If I help them, what would happen to me?” The truly great people think, “If I don’t help them, what will happen to them?” They don’t do it expecting something in return. They do it because they feel it’s the right thing to do.

[7]Paderewski later went on to become the Prime Minister of Poland. He was regarded as a great leader in Poland’s history.
