Now, I know that there were many factors that made it possible for me to do that. Most of them pure luck. The place I was born. Etc. But I still did it.
Also, it's not the greatest book ever. If I did it again, I'd do it much better. If I would review it, I'd give it, perhaps, 5 out of 10. It's not written very well, and the content could be better too. There are things in there I'd cringe about now.
But I still wrote it. That's not bad :)
