I would never quit if I were Flappy Bird developer..
As an avid gamer for 3 decades, I have always dreamed of making games. Back in the 1988, my friend and I wanted to make a game. We built a website in anticipate to promote the game (that was before blogs were popular) but we didn't really have the energy, passion and technical know how to write a game. At one point, 2 years after iPhone was released and many people are making money writing apps, we wanted to tap on that platform to write games. I bought a Mac with the main intention of studying iOS programming. Last year Dec, we even planned to take a week off and take a iOS programming course. So, it is with envy that I see successes of Flappy Bird, a game so simple, it boggles the mind on how it became so popular. And the natural thoughts of the developer quitting despite potentially making US$50,000/day is that he must be insane.. or weak. If I had $50K a day, I would shut off internet and go to the beach sipping premium coffee.. or I would buy a bungalow in Cameron Highlands
