The art of thankfulness

The attitude of thankfulness is really an asset. It costs you nothing, but you have everything to gain from it.
The attitude of thankfulness allays or even prevents us from envy, bitterness or anger.
The attitude of thankfulness makes us a lot more happier.
There are always something to be thankful of no matter how bad the situation is.
This world we lived in is not perfect, but...well, we still have a world to live in!(At least this world is liveable as compared to Jupiter, Mars, Uranus etc)
A person with no shoes can be thankful that he still have a pair of legs and able to walk.
A person with no hat can be thankful he still have a head.
A person who is blind can also be thankful that he can still hear, that he can focus on hearing beautuful tunes, melodies etc.
A person who is deaf can also be thankful that he can still see.
Even a person dying of cancer can be thankful for the time spent meaningfully during the last days with loved ones!
The point is:- Why focus on the things that we do not have or unpleasant things in the world and be angry and miserable? Instead be thankful for what we have, what we still have, and what we are going to have?
Think the best of everyone and everything.
This makes life a lot more happier.
