In the information overload we often find ourselves with, one must wonder what's important, what's relevant, what we need and what do we have time for.

Which means we have to be thorough in finding out what is useful and what is the product of mere curiosity, i.e., useless time wasting knowledge in our productivity-obsessed world.

Alas, too much productivity might actually stiffle your own self-development, starting with one of the most important soft skills for the current and future creative professional: curiosity.

I bumped into this via Brain Pickings, which deconstructs a 1939 (!) paper on this issue:

[one must wonder] whether our conception of what is useful may not have become too narrow to be adequate to the roaming and capricious possibilities of the human spirit.

Geeks will know what I'm talking about. You must have heard at least once, why read that blog, why explore that imageboard, why do you read and watch so much useless junk? Well, "useless" is a very dangerous term, specially considering the importance of idea association for creative production.

Often we're led to believe useless knowledge is a productivity killer, because it makes your mind wander and you lose focus on the actual work.

But as it seems, the more you broaden your interests, the more productive you'll be in terms of idea generation. So useless knowledge might just be the productivity boost you need to do something truly special for yourself and others.
