Undergraduate / "Curious to know all of it." - Essay on choice of CS as a Major for Undergraduate [5]

So this is my absolute first draft for the essay on describing why I'm applying for a major, which is Computer Science in my case. I'm an Indian student so have little idea or guidance on how to write essay for admissions so please excuse if the format or something else is wrong. So here it is -

"How do you know all that?" Even I ask sometimes myself, what's so special in me that somehow people think I'm just naturally good at computers? I think the better part of that expertise is a result of my curiosity. When I was curious about how internet worked, I wasn't satisfied reading the books. I published my first simple HTML website at the age of 12. It was great, anyone in the world could see it, but it didn't look quite good. Again, I was curious on how other websites looked so beautiful while mine was so dull. Which then resulted in me learning CSS and Javascript. Now my websites looked great, but again my curiosity kicked in, "My website's static like a photograph, how to make a website which is dynamic like a movie?" which is how I learnt various other computer technologies such as PHP and MySQL.

But it wasn't only about the websites.

My father got me a computer at the age of 10 and taught me how to use the internet. Not many can say that, but internet improved my life a lot. I was not satisfied with the computer classes in the school, but now I could learn it myself on the internet, and so I did. Apart from web development I got into app development, graphic designing and competitive programming. I knew I wasn't the only one with such curiosity and interest, so with my two friends in school I founded a computer club with the school's Computer Department, of which I was appointed as the President for two years. While in the club I managed two Inter School Technology Symposiums with over 300+ participants and published and edited the school's IT bulletin. I've made websites for many friends and even startups, and android apps with over three thousand downloads in the Play Store. But I don't want to stop just here, my curiosity hasn't dwindled a bit, and I know I still don't know all of that."

The essay word limit is 300 words and this is 334, so I obviously need to cut it down. Suggestions and criticism are welcome, and thanks in advance. :)
