I did this because I am behind (my Christian School was just awful for the most part, physics was God's love and math was for liars and moneylenders), and I'll probably never, ever catch up.
But still, I am trying to improve. But sometimes I talk to folks who don't work as hard at my tradecraft. They make fun of other folks who do. They try and shape the field to suit their lazy "this didn't outright fail so it's success" mindset.
Odds are, if you're a programmer you ARE behind. The field moves fast, no one does post-graduate teaching. Conferences are hit or miss and taught by the same folks. You need to work hard to fix it.
