“I learned this, at least, by my experiment: that if one advances confidently in the direction of his dreams, and endeavors to live the life which he has imagined, he will meet with a success unexpected in common hours.  … If you have built castles in the air, your work need not be lost; that is where they should be. Now put the foundations under them.”         

Henry David Thoreau Walden
