Feeling upset

I am a University student, majoring Computer Science, and now am entering the 3rd year, my life of undergraduate has passed 50%. What I feel now is upset, because still I can do nothing, I can just write a simple code and know a little about algorithm and network, and computer architecture. Having learned computer-architecture was something good to me, like I could go one step up and can see the map of computer broadly. But, what I can do is a little. About English, I have really advanced in writing and reading, especially reading, I am not fear of read lengthy article anymore, but still has problem in speaking English. I can speak almost everything, but it takes lag a little bit, conversation is a real-time processing, and I need to be more sophisticated that I can react more quickly.
These things above, is the main factors why I am upset, because there are more sophisticated students who are same age as me in the world, and I have to catch up. I originally thought that the fact I can not speak English was something I hated, but this year, I realized that there are a lot of advantages that only me can have as a English learner as Japanese. So I don't care about that, but anyway, I am determined to master English, so I wanna go more quickly, and this is why I am upset. Next, about CS, I feel upset but I think I don't have to be. because when I went through the online course "CS106A" which is offered by one of the best University in the world Stanford, I felt the students there do more or less same as I did so far, this is why. But one thing I started really concern about is that my attitude, watching those lectures, I noticed the students are really interactive, ask questions even if it is a small thing, I think this is important to have classes, and this is one element that divide the university and online university. Interacting with lecturer is exciting and making it more easier to learn.

Now, I've got what I have to do, be more positive in learning, ask questions if you have. Learn example by students at Stanford, imagine how they act if they were here. They're gonna become the best, now let's catch up and go over.
