I just don't like the idea of not being able to work on whatever I want. The taste of having customers direct customer that you serve directly is very different than when I have in the corporation where you just trick a little cock in the machine and it take so long to reach end users. In my case I set a target to quit my job when at least I have one or two KMR which is enough for me to boost the confidence that I will be able to do both this  and then go back to Vietnam.
