If you have a bad habit then make it use of getting into good things..That burning feeling. The feeling of being powerless.
However people can't stop smoking ,but make it useful for your studies ,by putting a target of some papers to study ,When complete a bunch of papers then go for cigar,and relax..
Not for everyone but for someone this post will be helpful,im not encouraging smoking but getting good things out of bad is a wonderful thing.
This picture is not a sign of motivation but for the sign of overcoming the problems in your life. leave the personal,family and financial situations aside and start concentrating on studies that will make you a challenging person in the society.
