Why is spoken Tamil so different from written Tamil?

Why is spoken Tamil so different from written Tamil?
ரோட்டில் நடந்து கொண்டிருந்த சிறுவன் திடீரென நின்றான்.
ரோட்டுல நடந்துக்கிட்ருந்த பையன் திடீர்னு நின்னான்.

Take a look at http://ta.wiktionary.org/wiki/%E0%AE%AE%E0%AF%81%E0%AE%A4%E0%AE%B1%E0%AF%8D_%E0%AE%AA%E0%AE%95%E0%AF%8D%E0%AE%95%E0%AE%AE%E0%AF%8D : "விக்சனரிக்கு வருக! இது சொற்களின் பொருள், மூலம், பலுக்கல் அடங்கிய, கட்டற்ற பன்மொழி அகரமுதலியொன்றை உருவாக்கும் கூட்டு முயற்சி." What?
If someone spoke to you like that in real life, what would your reaction be?

Why do you think this difference exists so much in Tamil? English doesn't seem to have this much difference. If you know any other Indian language, does it have this difference too?

Being intelligent can be dangerous

Whenever I complained about the college 'system' and things, I knew deep in my heart that there must be something wrong in me too that makes it a problem - "it takes two hands for a clap" they say.

Today, I came across this page: Your high IQ will kill your startup
It explains at least part of (what was) my issue.

People who are born intelligent start off life with everything easy for them. They don't have to work hard to get good grades, they never really have to do much to get ahead. The major challenge of early life is school - and school is designed for average people. So intelligent people just breeze through.

But there is a point where every intelligent person faces something that requires more than intelligence. It requires hard work, it requires the ability to fail, it requires being able to do tough tasks, boring tasks. For the first time in their life, in spite of their intelligence, these intelligent people are challenged, and they start failing. Like when they first attempt to create a startup.

And that's where most of them retreat. They focus on things they can't fail on, and ignore the other important things. They start to blame other things (like the school system). They procrastinate. They refuse to face new problems because they know they will not be able to handle them, and this does not fit into their worldview that they are invincible.

Thankfully, the "things they can't fail on" I chose in college were things like programming competitions and 'robot' making experiments, which turned out to be a not-too-shabby choice. Still, it's good to be honest to ourselves and realize where we screwed up. I hope I've learnt to digest and climb over failures these days, or at least am learning to do that.

I also found a similar link meant as a letter to Linus as he was exhibiting the above syndrome: Curse of the Gifted. Try to generalize the things there while reading, instead of reading in Linux's context itself. I especially liked this part:

"there will come a time when your raw talent is not
enough.  What happens then will depend on how much discipline [...] you
developed *before* you needed it, back when your talent was sufficient
to let you get away without."

It would seem I did not develop much of that discipline, but I'm trying to make up now. It's never too late in life to do the Right Thing.
