请帮忙修改一下有没有语法错误或者不地道的表达,一篇日记
Today,actually quite worth to mentioned in my life,one of my best friend said one word really hurt me and gave me quite a big a shock.
This evening,we went to laboratory and do the experiment,which was really a long period work.From 7:00 p.m.to 11:00 p.m.And I chose a very bored subject,nothing I needed to do except wait.
During that waiting time,I have a short conversation with my friend,talking about our future,about my studying abroad,about my major.She said '' I don't really think that you are fit to specialize in bioengineering..."
Hearing this,I am really not comfortable.It goes without saying that to some degree,this is the symbol of my failure in my 3 year's college live in her eyes.I am really lost for words.
After a deep consideration,I understand why she said so.To be frank,if you ask me what I like most,surely,my answer goes to computer,internet and website building.Sometimes,I really feel that bioengineering is quite bored,it's too abstract and theoretic.I like experiment,and I like the experiment what I am doing for my graduation essay.But it is also true that my heart is not totally in it because of many reasons.
Maybe it is time for me to cultivate my experimental skills and develop a strong sense of responsibility,to widen my horizon on my major and to prepare for my future life.
