Why gratitude is necessary in reference of Dr Kalam ?

As we all know about Kalam Sahib, he was a genuine individual, a unique personality, a renowned scientist. After all he was a great human who have shown that humanity is still alive and anyone can be great by their behavior, he believed that never be arrogant and show ego because god has never made anything waste. He said that never show your disrespect towards someone because even a gold medal winner has to put his head down in order to get  the medal. He always says that when we are given problem, so it's ok because beautiful photos can be made from negative version of photographs . He believed that being educated and being literate are two totally different things ,today humans are just focusing on making money, but we must realize that money is not everything and most of us have realized this in the time  of pandemic. We must know that when nature brings something then it is the result of our acts only and we need to be more conscious about our environment because we humans are  deadlier than this virus for our motherland , we are over  exploiting our resources and are thinking earth as our private property ,but it is totally wrong ; we must show our affection towards our very beautiful planet, and we must share love with each other, because we all are humans, and we have a fixed life tenancy, Therefore we must utilize our resources very wisely, and in a very decent manner because everyone is unique, show your genuineness towards each other, care for each other, support each other, don't poke one another ,show harmony and brotherhood because these are the things which shows our upbringing, life is one so please use it wisely because we all came one this earth in free hand but we leave this earth with plenty of memories and emotions, money can give us leisure, but calmness is something we gain, money can give us food, but hunger is something we gain ,money can give us home, but family is a sentiment which we feel, money can make us rich, but wealthy is something that money can't. For being wealthy true soul and a cheerful heart is required. Since spend happiness and get happiness we must follow, as smile is our first introduction and smile is a free therapy as well, we must never run for something that don't deserve us because life has always planned many things for us which are just overpowered in every sense, which is beyond our imagination, beyond our zone  because life is a gift of god to us. So use this gift wisely as effectively as possible and don't let someone manipulate you because when you are going in a right direction then so many people just try to seduce you to remove you as their obstacle. Therefore, just listen to what ever your heart says you to do, because you are enough for yourself, there is  freedom in not belonging so try to enjoy your own company, be your own reason to smile.
