Quitting a job for the first time

I had been a non-stop English language teacher and teacher trainer for 17 years. I had never been absent from work unless I had been really ill. I had never quit a job, but I did, at last, on July 18, 2014. Why is this relevant? it may seem like an ordinary decision for me, a simple mortal, to make, but no.. whoever knows me should also know that my life has been being a teacher; for 17 years I had woken up every single day just to go to work and come back to sleep and wake up to another work day. My life WAS only about teaching. My passion was all about teaching... until I decided to stop, for the first time in my life.
I decided I didn't want the job I had: the best-paying job I had ever had... what some called "the biggest opportunity you'll ever have, Elena!". I thought to myself: "Am I really this? only this? this job?". It had clearly begun as a challenge, and it cost me lots of sleepless nights and health problems, but I finally learned 'how to do the job', and I simply got restless. Money never meant a thing to me, so leaving became a very attractive idea... the only attractive idea. Especially because I was leaving for something my heart was aching for: to go and help in India. Why not in Colombia, my birthplace? well, simple: because many people like me, born in my own country, have the very same skills I have and can help, but very few like me were able to go all the way to India and help with nothing but my skills and was was in my heart: an illogical, indescribable love for that country. So I left.
