Of the left brain of the right brained people and vice versa

1) I am a right brained person, according to the test I took at a training at my company. It was a pretty useless test, if you ask me, because the test only checked what I liked to do, and not what I am good at. Those two are entirely different things although people often confuse them as similar. I like doing the right brained stuff but I am good at the left brained stuff. So what am I?
2) The 3 Idiots, which is entertainment mixed with a lot of gyaan - a LOT of gyaan, which killed it for me - gave fundaes about finding your true calling in life. Now what exactly does it mean by "the true calling in life?" Is it the thing you genuinely like doing the most or the thing you are the best at? The movie, while being good, is definitely not a masterpiece, and after a Hirani classic like Lagre Raho Munnabhai you are actually let down. Moreover, the way that it has looked down on achievers and praised the under-achievers is actually pretty naive. And ignorant of some basic facts about under-achievers. And the irony is, the movie is more appreciated by the achievers and those who were not meant to achieve :). But more rant about the movie later.
3) I owe a lot to the left part of my brain, and that is what actually made me graduate from the best colleges in the country. And everything I am today - which is not much, I have to admit - is because of the left part of my brain. Infact, the right part of my brain is responsible for my poor showing at both IIT and IIM. I could have probably topped there too if I really wanted to and allowed my left part of the brain to take over. But then again, it is the right part of the brain which really makes me happy- and there is nothing I can do about it. So while I do have the potential to be a Rancho or a Chatur, my right brain and my quest for following my dreams has made me a Farhan - or a Hari - or whatever the name of those two losers in 3Idiots was. But it has also made me happy, happy than I ever could be by being a topper or anything. And this is where 3 Idiots fails for me - a character representing me.
4) Remembered the venn diagram representation of the ideal job (Courtesy: Bud Cadell). Imagine three venn circles representing work you like to do, work you are good at and work that pays good money. See the diagram below. This is a great way to reflect on your work and are you doing what you are actually doing in your life. And what should you do to be really happy.



I tried putting my own perspective on the venn diagram and the results were not positive. These were the results
a) My current job was probably outside the Venn Diagram: I am not very good at it, I definitely don't like it much and it does not pay good money. Well, it pays okay but not good money.
b) The work I was good at was mostly left brained things like number crunching, quantitative analysis, qualitative analysis etc etc while the things I liked doing were creative writing, chattering aimlessly, playing sports, doing plays, and the like. Almost a certain mismatch between the two. Except probably for solving probability puzzles and cryptic crosswords. But the best was thinking about what are the jobs that actually pay money. These skills include cock sucking and ass licking of your boss across the different industries. Whatever you do and your other skills become totally useless. So my venn diagram became the following.



And now I am totally confused. My left brained skills and my right brained passions have left me little choice, about what to do. The venn diagram leaves me with only the following options then:
a) Open a Sports Analytics Company
b) Go Around Philosophising
c) Become a Creative Writer
However, being a left brained person, I am also try being a bit practical. And that practical aspect of me is afraid to take the next big step. Of quitting the current job, and doing something I like. A step towards being happier. At work. :)
