i am also plan the same. but my reason is not about cuurent company are bad, but i just want to be free.

i am looking flexible work hours, not limit to 6-9.

Was thinking of doing grab/uber part time last year. I have 2 cars....one registered 2008 and another one 2006. Both cannot use for grab/uber cos not meet requirement. I cant be buying a new car just to drive grab/uber....crazy. So drop the idea and sell my kidney

It depends on your salary range. If you have net 4K above now, don't quit, do part time first. It is not easy as expected to be full time driver, somemore once it becomes habit, it is difficult to get other job n you are any career advancement u might get..
