For 10 years I was never late for work. After that time passed I stopped caring. It was a test of self discipline at first. Time is only important if you make it important. Really what matters more is what you do during that time.
Meditation and learning to take the time to sense what is happening around you, I have always felt is important. Giving the body time to just be and not always stressing is hard for me. I always think about what is coming and how to fix things that can be fixed. The start and end of a line.
