You can't ever go wrong with Gratitude

According to Wikipedia,

Gratitude, thankfulness, thanksgiving, or gratefulness, from the Latin word gratus ‘pleasing, thankful’, is a feeling of appreciation felt by and/or similar positive response shown by the recipient of kindness, gifts, help, favors, or other types of generosity, towards the giver of such gifts.

I once heard somewhere that when you appreciate a finger shown to you, only then will be qualified to see the entire arm. This simply means that when you show gratitude for the little things given to you, then will you receive more. A simple 'Thank you' will go a long way to prompt your benefactor to do more for you, and not only that, he will know that he is being of good service to humanity.

You shouldn't always be at the receiving end. Giving to others is also an expression of gratitude for all the blessings you have received for if you're really thankful, what do you do? You share.

"Gratitude can transform common days into thanksgiving so, turn routine jobs into joy, and change ordinary opportunities into blessings."-William Arthur Ward.

Always be grateful. You can never go wrong with that.
