Trends matter. No matter what you’re trying to make happen for yourself, you cannot neglect looking at the trends. You are probably focusing too much on your feelings if you think that one negative health test means you definitely have a debilitating disease, or a bad day at work means your life is awful and you hate your career, or that one fight with your partner means you are in the worst relationship ever. Zoom out and look at the trends. Don’t just look at snapshots. Trends are more important than feelings. Don’t just look at one data point, or one snapshot, an n of one — instead, collect some more data and you’ll get to where you want to go, faster.
