Growth is staying calm when the plan changes by text at the last minute.

A plan changing at the last minute is mostly an annoyance, and what it costs you depends on the next thirty seconds. The irritation is automatic. What you do with it is not, and being able to take new information without turning it into an event is one of the more useful things you can build.

When the next message lands, wait before replying. Ask what is actually lost, which is usually less than the feeling suggests. Then adjust, get on with the evening, and notice how much easier you become to plan things with.
