Pursue of happyness..

Sometime, I think I shouldn't be complaining all the time. I should be satisfied although I've never been satisfied in my whole life. You can say I am ambitious, but who's not?!
I can still remember the first lecture I attend at UW. The director of CIDR said, be persistent is the top thing to survive in America, then you will be fine.
I am persistent, that's deeply in my bone, that's part of me, that's my personality, but I am, yeah, I am just fine. But fine in English doesn't mean you are great today, not even good. Fine just mean, while, you're not bad, you are just okay.
So, now, I am just okay. Mckinsey is driving me crazy. After the invitation email, there is no any further answer for the questions or confirmation. Everything just stopped there.
