Albert Schweitzer said it better:

I do not believe that we can put into anyone ideas which are
not in him already. As a rule there is in everyone all sorts of good ideas, ready like tinder. But much of this tinder catches fire, or catches it successfully, only when it meets some flame or spark from the outside, i.e. from some other person.

Often, too, our own light goes out, and is rekindled by some
experience we go through with a fellow man. Thus we have each of us cause to think with deep gratitude of those who have lighted the flame within us. If we had before us those who have thus been a blessing to us, and could tell them how it came about, they would be amazed to learn what passed over from their life to ours.
