I think you are making a very bad mistake. Just listening to a podcast... come on.. don't do this to your family. The podcast is selling their services and building audience for future products they will offer.
Think twice
Don't quit now, generate ideas while at job, start research and then plan accordingly.
There are so many incubators that could later help with your idea/prototype.
I didn't downvote, but I suspect the reason other people did is because he has considered these things. He already has a dozen apps on the store that make between 100-150 a day. He didn't just completely jump off a cliff.
Here's the thing: the OP did not mention that he has some apps that generate $100-$150/day already making the blog post looks like he's a risk taker. (hint: it's how you drive pageviews, no offense OP, but let's be honest until you fix the blog :)).
So you're right based on the blog alone, but not necessary 100% right had the OP exposed his side income.
