Only by doing so will I actually motivate myself to do the extra work required to succeed. You do not need the whole of your career planned out in front of you in order to be motivated. But you MUST have some sort of focus. Strategies to help with goals. If you achieve your contract, give yourself a break or a little reward.
Perfect practice makes perfect.
In other words, you will perform in your exams as you have revised for them. Revise in a professional, serious and well motivated way and that is how you perform on the big day. If your revision is sloppy, your exam script will be too. Sustained hard work always pays off. The importance of positive thinking cannot be overestimated.
