I'm sorry to hate but it's extremely rich to write

> Do not send me anything longer than you would send to a crush. Some people email me six-paragraph essays about the time they saved a cat from a tree

...in a rambling piece that is not written with much consideration for the reader. I know this is just a blog post, ostensibly written for the author's younger sister, but if the author really wishes to position himself as someone to take advice from, he should make some effort to make his ideas digestible. I would suggest he include some transitions between ideas, bother to do some research to back up his claims instead of e.g. referring vaguely to an experiment he heard of supposedly involving "lucky" and "unlucky" people (truly sounds like science).

And for the love of God don't tell me right off the bat that you assume I'm going to keep reading, let alone read closely enough to "notice" anything about your writing. Yuck

Finally, while I know it's popular in Silicon Valley/coastal tech types to use the language of agency to justify being an uncharitable dick to people around you, the spirit of this particular stanza is helpful to deploy only in a small number of settings, generally low complexity environments where the stakes are low and there's a lack of psychological safety, and you desperately need the paycheck.

In any event the good ideas here are largely betrayed by the author's bad writing and overgeneralizing his experience working in coastal tech. Do yourself a favor and find other role models
