uber driver yesterday told me his energy hack after a decade of truck driving. 3 scoops instant coffee, mix w/ few drops of water, heat it up, add chocolate and salt, eat the goo. "the most sustained energy you'll ever have". all i thought was "this is stupid". anyway it works.

there is literally no reason to ever, publicly or privately, hate on someone young and ambitious. total downside for everyone. at best shows a ton of insecurity and discontent for the world.

the solution is to completely ditch labels like "high achieving" or "struggling." these distinctions aren't real. you are where you are, and education should meet you there. simple as that.

It is, in fact, possible for an education system to support both struggling students and high-achieving students. Just 0.0002 percent of the federal education budget is allocated to supporting gifted and talented programs. Apparently some people believe that's still too much.
