"Sometimes in life, you won't get what you wanted...

i have experienced this in some occasions in my life, when I missed to get placed in first 3 companies in campus recruitment and later got placed very late in a good company than those I missed previously...

But, when I received this as an SMS last night and thinking over that for long time, without getting sleep... I couldn't come to a conclusion that, I'm not getting something I want now and will I get much better at the end...?

Is it really happening in our lives?
