The act of being thankful cannot be overemphasized. This is because being thankful open up more doors to those who are thankful. Take a child for example. If you give a child some sweets and that child shows you real gratitude that you can see in his/her eyes, wouldn't you be compelled to do more for that child? Of course you would. The same should go for everyone of us irrespective of our age or size. We should learn to say thank you to whoever has done any good deed for us. We should always show gratitude.
Not only should we show gratitude because we are expecting more to come, we should also be thankful and really mean it. It should come from the bottom of our hearts without any inner motive or hide expectations. That way, we will able to show that that good thing which has been done to/for us if of great value and highly appreciated. And if we say thank-you and really mean it without expecting something more, we wouldn't feel disappointed if truly we do not get anything more.
It's as simple as that.
Let's be more thankful and show gratitude.
Have a blessed week.
