Time is relative, and our perception of time is different because are all different.
Just as you said, we should value each moment of our lives. Living in the moment makes it easier for one to focus on more important things.
It is good to make goals and plans for the future but we should'nt be anxious about it, instead we should focus on the present for it is a gift.
You're right man, the present is a gift. A lot of people lose track of the present as a very important period in their lives. We value time differently and what I'm against is not seeing the essence of rest in our lives.
