I love to use quotations to make a point (I have a page on here with some of my favourites).
My favourite of all time has been used by many, including Abraham Lincoln, to whom it is often attributed, however Alexander Pope seems to have first written it and he died 100 years before Lincoln.  (I guess that makes it a paraphrase rather than a quote but it’s still a good saying!)

“No one should be ashamed to admit they are wrong, which is but saying, in other words, that they are wiser today than they were yesterday.”

I basically use this one to justify whenever i change my mind (-:
The same Alexander Pope, an 18th century English poet wrote some other pretty cool and often used sayings:

To err is human, to forgive divine.
Fools rush in where Angels fear to tread.
A little knowledge is a dangerous thing.

Here are some other quotes I love, and which have helped me get through these first few decades.
