Instructions for Life

"Pay attention. Be astonished. Tell about it." I see this quote for life as something different. I understand paying attention and being aware of your surrounding and being supervised of the things we find interesting. But, why do we have to tell about it, that makes it sound like were vaunting about something others had not experienced yet. What if have changed the that part to "Experience it." I say this for the reason of telling someone about one thing is way different, then if they were to experience living in the moments you feel are amazing as well.
