Roses?

Being a sort of gloomy day, I have been exploring the internet instead of venturing outside and, while doing this, I came across this quote from Dale Carnegie, an American writer/lecturer, "One of the most tragic things I know about human nature is that all of us tend to put off living. We are all dreaming of some magical rose garden over the horizon-instead of enjoying the roses blooming outside our windows today".

Now, I found this interesting and I am just wondering if anyone agrees and or disagrees with this statement? Are we really spending too much time imagining a world that we think is ideal and would want to live in or do we venture out into the real world? What about an in between?
