Dots connected

Yesterday, I used as a teaching material the Commencement speech by Steve Jobs, founder and CEO of Apple computer. I used it partly because i thought it was quite inspiring to young college students besides its being good material to learn English with. Here is the gist of the first of three stories he talked about.
First of all he confessed that he had never graduated from college. He had dropped out. Why had he dropped out? The reason goes back before he came into this world. He had already been decided by his unwed biological mother to be put up for adoption(養子に出される）before he was born. His parents who adopted him belonged to the working class but they sent him to Reed college following the promise with his biological mom. He said he had "naively" chosen the college that was notorious for its expensive tuition. He felt guilty when he thought the whole savings of his parents were spent away on the tuition of the college, in which he could not see any value worth the money. So he dropped out. But he stayed around in the college as a drop-in, taking classes without qualification. He didn't have to take required classes any more that didn't interest him. He started to "drop in" on whatever class he liked (I'm afraid it was illegal.) In the mean time, he happened to drop in on a calligraphy class and he was fascinated by its subtlety and beauty. He was just following his curiosity. He never imagined of practical application of what he was learning.
But several years later, when he was designing Mac, it all came back to him. He came up with the idea of a computer that has beautiful fonts. He brought a sense of art into otherwise dry and inhuman gizmo. Since Windows is just a copy of Mac, if he hadn't designed the computer with proportionally spaced, multiple typefaces, there would be no computer that have them now. He said if he hadn't dropped out, he wouldn't have taken a caligraphy class. If he hadn't taken the class we would have no such computers with beautiful fonts. He concluded that dropping out was the best decision he has ever made.
Then he remarked that it was impossible for him to connect the dots (dropping out and caligraphy and Mac) looking forward. Yes, you can only connect the dots looking backwards. So you have to trust that the dots will connect in the future in a way you can't even dream of.
Good story, right? We should do our best in anything we are doing right now without thinking it can be useful for us or not. The dots will somehow connect in our future. All we have to do is to trust in it. Looking back I really think this is true. Maybe unconsciously we are trying to connect the dots.
