When it comes to life, there is a duality. It is the longest thing we have ever experienced, but it passes by so quickly and feels so brief. It's all too easy to believe that we'll have tomorrow, next week, and next year to do whatever we want. The fact is, however, that life is valuable and not guaranteed.
Tomorrow is not a guarantee, which is why it is critical to live your life today and not squander a single minute.
