The day you will set yourself free from physical world that day you will find inner peace. Today everyone is busy wants a big house and expensive car and comparing it to what other people have that is the reason people cannot find peace. Physical world is temporary not permanent but your inner self is permanent and true. Do not chase after things which you cannot get instead focus on what you have. Try setting goals within reach with a little competition. All you need is find yourself then you will see world differently.
