Commit to memory 

When we were kids, our teachers demanded that we should commit our national anthem to memory. Though a very challenging task, we did it because those teachers were committed to seeing that it was done. Hence, they took time to follow up.

 I can say their commitment got us committed too. Thanks to it we succeeded.

I learnt my lesson. If you commit yourself to a cause,  not only will you find it a joy to do it, but above all, you will succeed even if it is difficult.
