The most of the people are not happy now a days because of the way they think. If they get any problem they stuck and think day and night about it. They are living their life with full of sadness. They can find sadness while they are in the moment of happiness. Everything has a solution. They can't figure out or you can say that they are not eligible to understand the universe no matter how qualified the people are. If you know the people from 1600 back year they were not engineer, doctors and highly qualified from major institute, but todays generation can't stand front of them. There are many questions in the universe why the peoples are like that. BTW, I don't want to write an essay here. Just recommend to peoples that never do that you have around 55-60 years life line so invest it wisely and live your life. Bye bye 9 to 5 people. You will surely regret later after your death once you will see your life after the death, if possible.
