It is not possible to go forward while looking back.

1926 was the most significant year. Looking back, it seems that it was not just a year in the sense of time. It was a year of great realisation or awareness. It seems to me that at certain times of the history of man, the understanding of certain situations ripens.

I really don't know the Chicago School. You see, I never walk. I always take taxis back and forth to work. I rarely see the city.

You can't look back; you have to keep looking forward.

Looking back isn't going to help you. Moving forward is the thing you have to do.

I'm not a great one for looking back.
