In life , not everyone smiling is really happy! some are rich and yet have no peace, some have a good spouse but no money, some have money but no education. What really makes you to worry?
People has no contentment that is why it is difficult for someone to achieve true happiness. I am worried that I may not provide well for my family. When I was younger, I was worried that I might not get the job that I desire. People change that is why what contents them change too.
