Become faster at recovering than you used to be at collapsing.

Everyone falls apart to some degree under enough pressure. What changes with maturity is not that it stops happening but that it stops lasting. Getting back on your feet in an afternoon instead of a fortnight is a real and measurable form of progress, even if the falling apart looks the same.

After the next bad turn, note how long you were down. Do not judge it. Just have the number. Watching that number shrink over the years is a truer measure of resilience than never being knocked over.
