It was the summer holidays of grade 11. I was savouring the lazy atmosphere and the chilled attitude that had taken over me. My mother got to know to about the deteriorating children of nearby slum failing in computer subject through our house maid. She realised how vital the skill of computing is for anyone's future in today's world and asked the maid if I could help in teaching the kids computer. She was also quick to see this as an opportunity for me to take up a fruitful activity. The maid agreed happily and said to bring the kids over to our house. I must confess I was in no shape to sacrifice my holidays and perhaps a tad lazy for this initially. I started with some apprehension on my part.

This experience helped me realise that students failed because of 'poor quality of teaching' at the aided schools. It left me feeling responsible and a bit worried about their education and their 'future'. I went ahead with the basics of the subject first. For the first half of the class we would study using a writing board. In the second half the kids would come turn by turn to practice what they just had learnt on my laptop. I took classes on weekends. After I thought that I had covered a significant amount of lessons, I held a quiz session and awarded the kids who had performed the best with candies. This made the learning process more fun helping me retail their interest intact.

This experience gave me the joy of sharing ones knowledge. I realised how much I loved teaching anyone something I was good at. I savoured the feel of attainment obtained after successfully teaching them. I loved their questions, nods, 'yeses' and the mistakes they did during the class. Teaching the class made gave me a sense of leadership which I treasured. It'll let me make a direct impact.

There is several occurrence of "realised" shouldn't it be "realized" instead? Else, I like the tone you are taking and find the essay relatively easy to read although you could put more emphasis on yourself (Maybe use "I" more often)
