While I second this recommendation I would also think that it doesn't make much sense that most HR people would prefer a "classic" resume over such a piece. It tells you a lot more about a person WHY and HOW he/she started several different things then the fact THAT those things were done. Try to imagine how this text would read in a resume like style: strip out all the anecdotal things about how and why and just leave the "facts". To a HR person this would read like "Oh my gosh, this person isn't knowing what to start next." But with all the anecdotal parts it reads more like "Oh a person which knows how to train different skill by theirself."
