If your old posts make you cringe, relax. That’s proof you learned something since.

The discomfort of looking back is evidence that the gap between then and now is real. You are judging an older version by a standard you did not have at the time, which is not a fair comparison and is a genuine sign of movement. Someone who feels nothing about their past has not changed much. The wince is the measurement.

Let the old stuff stay where it is rather than deleting it, at least for now. Read a bit and ask what specifically you would do differently, since that names what you learned. Assume the current version will look the same way in three years.
