Which articles do you read, which books do you refer back to, which conferences do you attend? But more importantly — have you created any system that automatically curates the relevant topics? There is so much to read that the backlog just increases.

The real question is not "what should I read" but "how do I build a system that keeps me current without drowning in content?"
