Robert Brault

If you have lived, take thankfully the past.
John Dryden

You say grace before meals. All right. But I say grace before the concert and the opera, and grace before the play and pantomime, and grace before I open a book, and grace before sketching, painting, swimming, fencing, boxing, walking, playing, dancing and grace before I dip the pen in the ink.
G.K. Chesterton

No one who achieves success does so without the help of others. The wise and confident acknowledge this help with gratitude.
Alfred North Whitehead

You cannot do a kindness too soon because you never know how soon it will be too late.
Ralph Waldo Emerson

We should all be thankful for those people who rekindle the inner spirit.
Albert Schweitzer

Some people are always grumbling because roses have thorns; I am thankful that thorns have roses.
Alphonse Karr

Appreciation is the highest form of prayer, for it acknowledges the presence of good wherever you shine the light of your thankful thoughts.
Alan Cohen
