Don't know where to start

Right now, at the very present moment that everybody is burning the midnight oil to study the exam materials, I'm sitting in front of my computer thinking I'll start right away, but when I turn the PC off and try to read something I'm sure I'll look for an excuse not to do away with the studying. Have you ever felt like this? I'm positive you have, unless you're one of those book worms that are seen studying all the time. While a huge pile of work or books is waiting for you at your desk, you convince yourself that there would be no harm if you started tomorrow, or next Saturday, or on the 15th or any other round number! I always remember what Mr. Rakhshani said: "Never do today what you can put off until tomorrow." It's always like this rather than the other way round, isn't it? The story goes on like this until the night before the exam-that sleepless night-when you go above and beyond to finish reading all the materials once at least. On the day of the exam, stressed to death, thinking everyone else is ready but you, with those empty looks of yours when someone asks a question, you go to the exact place of exam, waiting for your executioner to show up and give you the test. You look at the questions quickly and you recognize you don't know some and the answer to the rest is so vague that you don't know what to write.

After the exam you promise yourself that next time you'll do better and that you won't leave all the hard work for one night, but when exactly that next time comes no one knows. It seems it goes on like this forever like a vicious circle you can't get out of. Maybe I'm too undecisive that I'm facing such problems....you tell me.
