Act-Smart-ism

Acting and pretending to be smart was kinda obvious to me all the time...
Today, I seriously learned a lesson...
I don't mind learning new lessons everyday, but not in the finals...
This is going screw up my life definitely...
I had my first paper today, and I am definitely not happy with it (after I realize something)...
The invigilator had a voice sounds like "nightingale"...High pitched than anyone else...
During the exam, I was copying/rewrite the answers to the booklet...
Due to my egoism and act-smart-ism, I cross the answers and rewrite a brand new one...
And I don't understand why I had such a confident that the answer will be correct...
After a short discussion (after the exam of course), realizing that my act-smart-ism went wrong...
THE ANSWER WAS WRONG !!!!!
I know I shouldn't sulking over it...But, I can't help it as usual...
There is nothing that I can do to change the past, and I lost 13 marks for that question, which is an unquestionable fact...
I consider my exam today zombie (half dead half alive), with no expectations that I'm going to get A or what so ever, due to my act-smart-ism....
I wanted to share this feeling with everyone: do not ever act smart, although you can act it the way you want, the consequence will be very stupid, and ended up putting yourself in a situation that you can't get through, which is still angry for yourself...
There is a Hokkien saying that: You can be smart, but don't act smart...
I wouldn't want this to happen again tomorrow (hope so), can't guarantee that I won't repeat the same mistake...I seriously hope so...
To overcome, only thing is to prepare well before exam (obvious)...The paper tomorrow is going to be tough and challenging...I wanted to conquer, but, see how, it's not the Alps or Everest...
NO MORE ACT-SMART-ISM...
You will ended up committing suicide mentally, as in sitting there alone and looking at the correct answer...
Confident is good, but it kills sometimes...All the best for tomorrow...everyone...
