Physicists know what's important, but they don't know what is true. Mathematicians know what's true, but they don't know what is important.

The main things which seem to me important on their own account, and not merely as a means to other account, and not merely as a means to other things, are knowledge, art instinctive happiness, and relations of friendship or affection.

Things which matter most must never be at the mercy of things which matter least.

You are important enough to ask and you are blessed enough to receive back.

Much Ado About Nothing,

Half of the harm that is done in this world is due to people who want to feel important. They don't mean to do harm. But the harm does not interest them.
