The difference between urgent and important may seem intuitive after thinking about it, but how many times do we confuse them while in the moment? Important means something significant or of value, while urgent typically signifies something that requires immediate action or attention. An oil change in 1k miles is important, but not urgent. Answering the doorbell may be urgent, but not important. A task can be either or both, and often we may feel that something we must get done is urgent when it is important, and visa-versa.
