I'm a full time vocal coach, I teach primary school kids in the day and private students from noon onwards. And I love it! The pay is very little compared to what I can earn if I worked in a marketing environment (where my academic qualifications are at). And if God willing, I want to be a missionary some day too!
The process to getting where I am now was very tough though, I had to fight very hard for my beliefs and ideals. And till now, some people in the family are still not happy with what I'm doing and the amount of money I bring to the table. The elders that I talk to always dismiss my work as something that has no value, and many have the impression that I'm just trying to live an easy life (because it SEEMS easy, and my hours are flexible).
It's the cruelty of a degree, results, material wealth, and merit-driven country and society. But even with the downsides, I still love what I do.
Working for money is pointless, there is no true satisfaction to be had from it. Find your purpose in life, and live it, even though everyone else wants to pull you into the 'flow'.
