Today morning my boyfriend sent me messages mentioning  that, his friend who will get the master degree this winter has got several offers.And the medium salary of the postgraduate students studying  engineering specialty is 15w plus one year.Well,it shocked me.Because I had been studying biology relative specity,and working still in reserach institute.People working in institues get the income much less than that.Even a Phd doesn't get that much money one year.So I felt a little sad and sent some depressed messages.As usual our conversation ends with unhappiness.Then I think about the question  that whether the industry or the ability lead to how much you should be paid for?Although the ability is the basic requirement,different industry people's salary has large difference. I feel unstastified and don't know how to change this situaton.I didn't give positive energy again.The biggest peoblem between us is that he always feels my negative.Actually I think the money doen't determine the level of happiness.But as we have been not together for a long time,I don't know how to experss myself in truth.It's hard for me to statisfy him everytime.Of course maybe my negative mood is too much but I have not  felt it.

         It seems that this article has been off the topic.But to be honest how much do I value in the society?
