Rule #22 Respect other people’s time. In the modern world, time is quickly becoming our most precious resource.

Every people time is precious because it just won't stop. Even though it is not stopping, we should have a more meaningful seconds and minutes and hours and days and years. We should make the time pass more enjoyable and happier. Time is precious but I think on top of that health be it mental or physical health is still the most important.

1st: mental health - happiness
2nd: physical health
3rd: all the others
