I once heard Dr. Robert Jeffress express his advice to those not ’feeling’ thankful.
"I have found that it is a lot easier to act yourself into a feeling than it is to feel yourself into an action."
From his wise statement I have surmised that the very act of giving thanks or expressing thankfulness will help us to begin to feel thankful. Once we 'feel' thankful we begin to take on an attitude of thankfulness. The attitude of gratitude!
