A living organism is an agent of bounded rationality that doesn’t pursue a single goal, but instead follows rules of thumb for what to pursue and avoid. Our human minds perceive these evolved rules of thumb as feelings, which usually (and often without us being aware of it) guide our decision making toward the ultimate goal of replication. Feelings of hunger and thirst protect us from starvation and dehydration, feelings of pain protect us from damaging our bodies, feelings of lust make us procreate, feelings of love and compassion make us help other carriers of our genes and those who help them and so on.

I updated the intro of Rules of Thumb for Human Systems with selections from Small b blogging.

Small b blogging is learning to write and think with the network. Small b blogging is writing content designed for small deliberate audiences and showing it to them. Small b blogging is deliberately chasing interesting ideas over pageviews and scale. An attempt at genuine connection vs the gloss and polish and mass market of most “content marketing”.
And remember that you are your own audience! Small b blogging is writing things that you link back to and reference time and time again. Ideas that can evolve and grow as your thinking and audience grows.
As Venkatesh says in the calculus of grit – release work often, reference your own thinking & rework the same ideas again and again. That’s the small b blogging model.
