Need a quote about hindsight?

Question

I need a quote about hindsight that gives this vibe:

It's easy to look back at things and make a judgement...

It's harder to use foresight....

I have already seen Billy Wilder's quote, "Hindsight is always 20-20." I need something original to prove my essay's point. If you could put the quote and the name of the speaker, that would be great!

If our foresight was as good as our hindsight, we'd be a damnsight better off! - My Grandmother.
