If you're sincere, praise is effective. If you're insincere, it's manipulative.
Johann Wolfgang Von Goethe
Instruction does much, but encouragement does everything.
Insults should be written in the sand, and praises carved in stone.
Dr. Joyce Brothers
Listening, not imitation, may be the sincerest form of flattery.
Mary Kay Ash
No matter how busy you are, you must take time to make the other person feel important.
Norman Vincent Peale
The trouble with most of us is that we would rather be ruined by praise than saved by criticism.
Orison Swett Marden
There is no investment you can make which will pay you so well as the effort to scatter sunshine and good cheer through your establishment.
We increase whatever we praise. The whole creation responds to praise, and is glad.
