Why your current condition is best for you?

There was a labour who was working in a very hot sunny day and he was completely sweating. He was smashing the rock and complaining to God about his situation. God sends an angel to him in his dream, the angel asked why you are unhappy and complaining, this is your native work forwarded to you from your forefathers. He replied what the hell is this, I work whole day and just get bunks in return which difficultly feed me. After that conversation the angel got permission from God to turn him into whatever he wants. The labour suddenly saw a rich man who was trevelling in his private car, he thought that this man is rich and powerful, having private cars and servants also. He asked angel to turn him into that person, the wish comes true he became rich, under shelter and happy but when he once went outside without his shelter he realised that his skin was burning because that rich man had that disease, he noticed it's sun who is burning him so he thought that if i became sun i will be more powerful and wish comes true, he is the sun now, he is the only natural source of heat and light but one day clouds covered him completely, he can't even express himself and feels that he is useless at that moment. Now he want to be cloud, wish comes true and he is cloud now, able to hide sun and causing the thunderstorm but he noticed that after his all efforts he can't affect the mountain, he now became a mountain, the fixed and powerful, very happy at that moment. One day he noticed that he is getting hurted and the reason is that a labour was smashing it and one day he will crush the mountain completely. The cycle ends and the most powerful person than everything was the labour. He woked up and thank God for the blessings and power that he observed he has.
God is the best creator and we are the best creation, the thing is that God doesn't make copies he made each and everyone of us unique, that'swhy we sometime think that we are not at the level we should be by comparing us with someone else but the one you are comparing with is at his best and you are at your best, so the comparison can't even exist, so be grateful.
Holy Quran says that " Maybe the thing you think is good for you is bad and bad is good, Allah knows but you don't".
