Showing gratitude cannot be underestimated, is a feeling of thankfulness. Gratitude could change our attitude and become an aptitude, taken away our solitude and lifting above altitude.
Gratitude shows our appreciation, gratitude could serve as an encouragement for the helper. Even God appreciates when we thank him not when we always ask, ask and ask.

Am always grateful for the gift of life, i didnt pay for it, i didnt earn it, i did nothing.
Just by the mercy of God
