Not sure I totally agree with that statement. Eventually dreams do end. When my father got older he told me that he accomplished everything he wanted, had all that he needed, and didn't have anything to look forward to. Soon after he developed Cancer then died a while after that.
As I get older I've found that my list of wants grows strangely small. When I'm asked what I want for my birthday or Christmas it is usually just "time with my family".
Wow!!
This is so unusual of humans,, our needs are always insatiable, the reason I said that dreams never ends. But like you said, those experiences teaches more than mere talk.
I have a lot of things on my list I want to be able to accomplish, I sincerely hope to.
One of the benefits of youth and energy !
.... and also a curse if you can't get it done. ;)
Really, it is.
