Well portrayed by Mr.Shah, but one thing I would like to add that is to focus on a single goal is good but sacrificing each and everything would be suffering. If a person studying for 8 hours daily and keeping up the same routine may lead him to fatigue or may lack confidence. So the best way to get succeed is to study, also manage your social sector too. A day or two in a week for refreshment is good for brain, which will boost up your mood and will give you motivation for continuing up your preparation.
