There is a story that when going fishing at sea, fishermen usually put a few catfish in a group of sardines to keep the fish alive.
No matter what age you are, competition is always as fierce, and those with advanced competitiveness will always win. If you fail but don't realize why you failed, then this factor will always be accompanied by subsequent failures and you still haven't discovered it. You will still make the mistake in the long run, slowly admit that you are garbage, fail in pain, and have less and less faith.
