Here are a few of the changes I noticed then and am noticing again now:
1) My lazier thinking evolved from counterproductive commiserating to reflexive systems thinking. Each description of a problem forced me to ask and answer: What policy can I create to avoid this in the future?
2) I was able to turn off negative events—because the tentative solution had be offered—instead of giving them indefinite mental shelf-life (and “open loop” in GTD parlance), resulting in better sleep and more pleasant conversations with both friends and business partners.
3) People want to be around action-oriented problem solvers. Training yourself to offer solutions on-the-spot attracts people and resources.
