    Today the youngest millennial in the world turns 22 and tomorrow the oldest one turns 38, so keep that in mind when someone uses “millennial” to mean “kids these days”

    Meme version of "Bronze Medal" comic.

First five panels show someone being awarded an olympic medal and celebrating in loud and obnoxious ways. Over his face is a curve with a point at the minimum.

The sixth panel reveals that this is just a local minimum on the curve that was awarded "3rd place", and that there are two points that are much lower.

    I think “even senior developers have to Google things!” is true and important but misses the point It’s like saying “even concert pianists have to practice!” The lesson isn’t “We’re all faking it,” it’s “Searching/practicing is necessary to get better and that never stops”
