Listening to a podcast dealing with <waves hand at all this politics & news> and a guest mentioned their father pointing out how using a chisel (in woodworking, stay with me) takes all the strength of your arm, and focuses it on the razor edge of the tool & that's why it works; lots of energy focused into a narrow purpose.
And the likened that to how we can be effective in a climate where we face battles from all directions: choose one narrow area where *you* can be effective & help.
