Some good quotes to say thank you for helping include Shakespeare's simple and direct words, "I can no other answer make, but, thanks, and thanks" and Marcel Proust's deep message, "Let us be grateful to people who make us happy; they are the charming gardeners who make our souls blossom."
Respond to a gesture of help at the earliest. If you are busy, keep the message short with a quote from John F. Kennedy, "We must find time to stop and thank the people who make a difference in our lives." Tailor your message to suit the recipient and the situation. A student can thank her teacher by quoting Henry Adams, "A teacher affects eternity; he can never tell where his influence stops." Add your own words of thanks to personalize the message.
Make use of humor where appropriate. For instance, thank a friend by saying, "The only people with whom you should try to get even are those who have helped you" or quote Benjamin Disraeli, "I feel a very unusual sensation - if it is not indigestion, I think it must be gratitude."
Write a personal note or an email, make a telephone call or choose an appropriate e-card. Use correct forms of address for the receiver, while keeping the tone simple, sincere and respectful. In addition to appreciation, express your wish to make good use of the help provided and return it in the future. You can supplement your message with a bouquet or a small gift.
