In persuading myself to revise, I have to note an unfortunate truth about myself

My friend sent me a quote “Revision is like foreplay for exams, the more you do, the better results you will get”. I don't know where this quote is from, but I will say that it proves difficult in many respects. When I still did/had the opportunity/inclination to do the sex, the best foreplay was usually a quickie. You see, that's me all over, the thing that gets me excited about anything is instant gratification, and that, I realise is strongly reflected in my academic attitude to date. Revision was always the day/afternoon/evening/morning before an exam, and no more. I think the only time my revision got the full day for an exam was when it mostly involved watching Fight Club several times over. That's not to say I won't work, or can't work, but there has to be enough of the instantaneous to create the excitement in order to want to put the effort in. To know whether it's worth it, you have to feel that it's worth it.
