[Question] What’s the best time-efficient alternative to the Sequences?

The sequences are pretty long, and even the Highlights of the Sequences and the CFAR Handbook are pretty long, even though they’re the next best thing. Much too long for me to recommend to the busy people in my life so they can try out rationality for the first time.

Akash made an effort to heavily trim down the Highlights of the Sequences, but too much was lost without the evocative examples.

What I’m wondering is: what is there here on Lesswrong, and elsewhere, that amps up someone’s intelligence/​rationality as much as possible, but is short enough that nobody looks at it and thinks “I’m too busy/​tired for this”? News articles seem optimized for this, they seem to gravitate towards <1000 and there’s some pretty strong market optimization pressures there. I’ve heard some good things about Scott Alexander’s blog.

If provably increasing intelligence/​rationality is too much to ask, then what affected you the most, what resulted in enduring, net positive change, such that after reading it, you had permanently diverged from the kind of person you were before?
