... I quit my job because my boss was a, let's say, not so nice person (mildly put). I was without a job for 4 months, and I got bored, so I sat down in front of my computer and started writing the first romance story that came to my mind. I didn't have ANY thoughts about publishing or becoming an author back then, but after I had 100K words on paper 8 weeks later, I thought "okay, maybe you should do something with that". Yeah, easier said than done with being a non-native. It took me another 6 months to gather the courage to take that leap of faith. Unbelievable, now here I am getting a bunch of books out to the world :)
So, lesson learned - never let your insecurities get the better of you!
