Dale Carnegie said this quote

Don't be afraid of enemies who attack you. Be afraid of the friends who flatter you.

~ Dale Carnegie

One of the tragic things I know about human nature is that all of us tend to put off living. We are all dreaming of some magical rose garden over the horizon - instead of enjoying the roses that are blooming outside our windows today.

~ Dale Carnegie

It isn't what you have, or who you are, or where you are, or what you are doing that makes you happy or unhappy. It is what you think about.

~ Dale Carnegie

Be wiser than other people if you can, but do not tell them so.

~ Dale Carnegie
