The phrase ‘thank you’ is so miraculous, as it embraces one of the most wonderful emotions of a human being - gratitude. These two magical words are like a badge of honor that demonstrates your appreciation of others for their hard work/ help/ commitment - which is hard for anyone to resist.
The effect of thanking does not end there. It also applies to you - the thanks giver. In fact, a study by the University of Pennsylvania has revealed that the act of expressing gratitude provides an instant boost to one's fulfillment, which could last for up to a month.
