I once was with somebody I liked very much -- an older person, when I was considerably younger than I am now. That person said, "Spend at least fifteen minutes a day weaving dreams. And if you weave a hundred, at least two of them will have a life." So continue with a dream and don't worry whether it can happen or not; weave it first. Many people have killed their dreams by figuring out whether they could do them or not before they dream them. So, if you're a first rate dreamer, dream it out - several of them - and then see what realities can come to make them happen, instead of saying, "Oh, my God. With this reality, what can I dream?
I know that blogging aficionados don't approve of posts consisting of quotations - but I don't care! I came across this recently and thought it was great, so I'm sharing it with you.
I also think that there's an alternative way of ending it - 'with this dream, what reality can I create?'
