This guy, through a combination of youthful good looks, utter lack of shame, and sheer hustle has managed to get himself onto the british top 10. But he can't sustain it and the song itself is utter crap; he never set out to make good music, after all.
So what's the point?
The author mentions Tim Ferriss and I see the parallels. Ferriss also "hacked" his way into the Chinese Kung Fu champion's position, by unconventional use of the rules, in a paper achievement lacking any real accomplishment or respect. To his credit, Tim followed up by writing several books of actual value, and never confused hacking a competition with actually being a kung-fu master.
Like Ferriss's win, this is a stunt, a conversation starter, a prelude. It's AirBNB's Cheeri-O's, or whatever they were called. A cool anecdote to talk about - and kudos to him, genuinely, and AirBNB, and Ferriss. But it's not a real achievement in and of itself, not one that I particularly care about, anyway. At the end of the day, you still have to make AirBNB.
So now what?
