Actually,i think it just has to do with your mindset on studying.
You should have an early rest,get up really.Sleeping too much does not help (it just adds to the laziness).Know your
priorities, take an hour or two to sit down and do your work,and please,for your own sake,don't think of what you
are going to have for lunch or other non-related stuff when you are studying. At the same time ,do not stress yourself
out .After you have studied,enough is enough, If you try to squeeze every formula from the text into your brain,It then
amounts to a complete blank. All work but no play makes uchiha-vegeta a dull person.Having a good diet is important
too,I am not asking you to eat like a monk ,no fried stuff and no...what ever they don't eat.The point is eating
some is good but don't eat too excessively as in too much. Procrastination is one big fat obstacle,you got to have
alot of will power to overcome it. Thoughts like "leave this sum to tomorrow " , "who gives a damn about
this essay". If you have a doubt, clear it IMMEDIATELY. Telling people how much effort you have put in just does
not cut it . In my opinion ,your results will speak for itself and it will tell how much effort you have put in.
That's about it. It 's the stuff that made me a sucess academically (there is also another thing). Sorry for
taking up so much space by writing a whole lot of_____.You feel in the blanks, either crap or useful crap. It really is
up to you.
