How can we learn if no pain?

Pain is the basic feedback mechanism that motivates learning. But are we only willing to learn until being forced by this most basic mechanism?

Thinking is hard. What will make you take initiative to learn something hard but (perceived by me) important to you, your future generation and commons?

May be you don’t think it is important because you haven’t see the effects now, or there are some symptoms but the reason is still in political (not scientific) debate, by the time the effects are so overwhelming that it is undisputable, it might be too late to change the fundamental trend. There are delays for the effects to show up, for our perception to recognize the effects and for our action to have an impact. How to speed them up?

Always be humble that we know only little. We need to learn more.
