Important and urgent things are jingles.

Take your time to do important things, and do urgent things at once!

Urgent things need to be dealt with urgently at this moment, so we should do it at once. If we miss this time node, we will miss it.

Important things, to make a plan, need to break down the task and do it step by step. You can't solve them in a hurry, so you should take your time!
