Quote for Today
“Without data, you're just another person with an opinion.”
- W. Edwards Deming

If a stranger insults me, I'll probably ignore it, as their opinion is meaningless.
If a stranger compliments me, I'll probably treasure it, as their opinion is important.
(one of the paradoxes for many people)
