No doubt that life is a comparison of various situations as the adjacent situation shows the state of mind by considering the TV Volume during running of a movie and running of a commercial. This screenshot is an apt state of mind and is well captured.
So one may be happy in one state whereas may not be happy with same conditions in different state.
So whenever you feel low in life look at a person who is downtrodden than you and you will realise that life has become more merrier for you and you will find yourself achieving success in life by virtue of comparison of two situations.
However this does not mean that you leave the success portion to God as unless you put in the efforts none is going to come and help you in the life.
