The good thing: you can read this book in about one hour. The bad thing: it's still to long, because basically it's an extended version of 'fail early, fail often', Beckett's 'Ever tried. Ever failed. No matter. Try again. Fail again. Fail better.' and Pasteur's 'In the fields of observation chance favors only the prepared'.

You will work hard, you will fail, you keep learning from it and go on. Now you know everything you could possibly learn by reading this book. I just saved you from all that bullshit about how God (and his angels!) direct our creative urges and procrastination is from Satan, the bullying against amateurs and all the Greek mythology.
