One hard day is a data point. Don’t draw a trend line through a single dot.

One bad instance says almost nothing by itself, though it feels conclusive while you are inside it. Every ordinary process includes days that go wrong, and reading a direction into a single point produces conclusions the evidence cannot support. What you need is repetition before interpretation. A dot is not a line.

Before concluding anything about yourself, wait for the second and third point. Ask what the last month looks like rather than the last day. If a pattern really is there it will still be there next week, and then it deserves a response.
