"Be hearty in your approbation, and lavish in your praise.” -American steel magnate Charles Schwab (not the discount broker), a quote popularized by Dale Carnegie
An aside regarding:
When you look for the bad in mankind, expecting to find it, you usually will."
— Abraham Lincoln
....
Excellent choice, Sabertooth. That is also one of my favorite quotes and I hope this won't be perceived as nit-picky, but it didn't actually come from Lincoln. I was impressed by it when I came across it in a positive-thinking book somewhere (I thought it was in one of Dale Carnegie's books, but I haven't found it there since), but when I went searching for it again to get the right wording I learned that its source was not Lincoln, but rather a far more humble source--David Swift, the director of the Disney movie Pollyanna...
"When you look for the bad in mankind expecting to find it, you surely will. Abraham Lincoln." —the character Reverend Ford, reading a fictional inscription on Pollyanna's locket, conceived by David Swift, Writer/Director of the 1960 Disney Film Pollyanna
Swift had derived the quote from one in the book that the movie was based on:
"When you look for the bad, expecting it, you will get it. When you
know you will find the good--you will get that." -fictional sermon of the Reverend Paul Ford in Pollyanna, by Eleanor H. Porter,
http://porter.thefreelibrary.com/Pollyanna/22-1So the earliest known source of this quote was the humble author Eleanor Porter, whose book Pollyanna (intended for little girls) and its message have ironically become the object of derision over the years. What is the point of this other than accuracy? Well, this and other misattributions have taught me to be skeptical of the attributions and wordings of popular quotes and to consider whether a quote that doesn't need a famous name attached to it may provide more useful advice than one that does. I find that Swift's quote holds up pretty well in my experience without Lincoln's name attached, but I still find it useful to ask myself if a quote would stand on its own and whether it holds true in the real world.
There is a corrollary to this. Nassim Taleb has advised that we should be
more skeptical of someone who wears a tie, not less. Taleb explained, "You have to ask yourself why he is wearing a tie. More often than not, he's not an expert. He just wants you to think he is."
