I sometimes hear that nobody ever dies wishing he had spent more time at the office. I bet that plenty of people die regretting the things they could have accomplished but didn't. Like, a guy who thought about making a personal computer, but lit up another doobie instead. The person who envisioned a library of downloadable music but thought computer programming would be too much work. Or the person who imagined a computer on a tablet, but couldn't work on it because Dancing With the Stars was on.
I hope that Steve Jobs had few regrets when he left us. He did so much that has improved our lives, even for those of us who are not Apple guys.
