I think you don't grow up until you stop worrying about other people's purposes or lack of them and find the purposes you believe in for yourself.
What comes first, the compass or the clock? Before one can truly manage time (the clock), it is important to know where you are going, what your priorities and goals are, in which direction you are headed (the compass). Where you are headed is more important than how fast you are going. Rather than always focusing on what's urgent, learn to focus on what is really important.
The TRUTH: It may not lead you to where you thought you were going, but it will always lead you somewhere better. When ignored, it will eventually show itself. The closeness of your relationships is directly proportional to the degree to which you have revealed the truth about yourself. It can be painful.
