Dissapointment in myself...

What is the feeling of being dissapointed with yourself? It is terrible... You will feel like cursing yourself all the way... I hate myself for that! When things happened upon others, we can alway ask them to cheer up, do not give up and so on.. BUT when things hapen on ourself, we will always never be able to do the same... We can not even persuade ourself... I think i must be blind!! Why i did not see the question properly???!!! First exam finished... And also get the result back already.. Next will be the second exam... First exam i did not do well in it which is a shame... I find that i am feeling bad part of it is because others get a lot better marks because they had the past year question and they juz score better... The lesson of this exam, next time just focus on the past year paper.... Huh... i wonder this time how will my score be...?
