Trouble motivating myself - need advice?

First of all you need to ask yourself why you are doing this assignment and why you are completing this application form. You know deep down, that It's because you want something out of it, otherwise why would you bother? I'm guessing it's a job that you are applying for, so what better motivation than thinking about being successful, and actually getting the job? You've said yourself you're not a lazy person, and eventually you will get tired of lazying around. I believe that should be enough motivation. One should always look for the next goal in life. Good luck.
