Very often people get into trouble because they actonsomething which they know only a little about, and it turns out that their knowledge is not adequate enough to deal with the problem they have.
If you can show a critic that you've learned something, you prove that you've understood the criticism and tried to acton it.
如果你能向一位批评者展示你学到了某样东西，那么你在证明自己已经理解了批评，并且试图采取行动。

If you're looking for something to change beyond yourself, if you depend on the behavior of others, or a change in your environment before you act, you're in for disappointment.
