small things do matters : saying thanks

people say that love is the most magical thing happens. but i know something that could be as magical as love. the word thanks.
since its rarely and more rarely used in this era, the word 'thank you' are said less properly. a proper-said thank you has such a hugeee impact. you know, people are happier if they know that they are useful for others. that's the point of saying thanks, letting people know that they have been really helpful, and means something to another.
what about saying thanks properly, more often?
