I grew up thinking that I'd be a Homo Universalis. I never made it.
Halfway through my 4th decade on this earth I admit I'm not a polymath. I'm not even a specialist in something; anything! I scan through the daily questions on stackoverflow but I can't find something that I have a definitive knowledge on.
Apparently I'm just a guy who fiddles with everything, but at the end of the day knows nothing!
