Being Perfect not only in school

I'm kind of a perfectionists, though the condition is not very serious. I'm still a student, it is not quite harmful. I think the situations is much worse when I get to work. Although, I have experienced tragically suffering from my perfectionism in school. That's when I did my terminal exam on Literature. I wanted my essay has amazing opening, and I supposed it to be the best essay in my class. I'd racked my brain to choose the cleverest words to put on my essay. Time out and I end up having not finish it yet. It was an awry essay instead of a perfect one as I expected. I even just nearly passed the average scores on that test. That was so bad. Another times, I had a presentation in History class. The day before, I had pulled an all-nighter frivolously changing my power point project because I wanted it to look cute and be neatly illustrated to my presentation. I keep yawning in class the next days and being notices by the teachers. Such perfectionism didn't do me any good.

Therefore, I decided to allow myself be spontaneous and slacking off sometime. I believe that my perfectionism will get me going and do my best. However, I don't want to be a extreme perfectionist someday.

Help me correct this writing, please! many thanks

Your essay is lack with supporting details for your topic. I think you will make it more better if you concluded explicitly what is the pros and cons of perfectionism...However, i see a little bit of it but I, as the reader, wanted more...

And the most important is the right shift of tenses...that a writer commonly get mistakes.

---Nobody is perfect. Butpracticemakes perfect --

Oh, thank you for your comment, I'll take in all these useful advices. I'll rewrite a better essay.

I like that first sentence! But the correction suggested by Saysi is important. Take away that s.

Also, let's say this in a clearer way:
I'm still a student, so I cannot do much damage. it is not quite harmful. I think the situations is much worse when I get to work. Although, I have experienced tragically suffering from my perfectionism in school. ----Ha ha, I really like this theme you are using.

Therefore, I decided to allow myself be spontaneous and slacking off sometimes.

I believe that my perfectionism will get me going and do my best. However, I don't want to be an extreme perfectionist. someday .

I take this issue from my own reality, so it's quite interesting and I have enthusiasm to write it. I think enthusiasm is very important because it helps people learn English more effectively.
