Your feelings are just normal youthful listlessness. It will pass. You could try getting REALLY DRUNK, but it won't really help. In a year or two, things will be a lot better.
Modeling the stock market is REALLY HARD. No one has done it yet. Don't fret over it. In fact, I'd say don't try.
You will probably have to wait a few more years to get research internships. That's just the way things are. Keep trying though.
Starting a company will get easier as you get more work experience.
Program committees for Academic conferences and Journals are not "double blind". The people reviewing your papers know your name and your institutional affiliation when they review your paper. Getting accepted without someone else's name attached is hard. Just keep at it.
Don't worry about the school you go to. Being an entrepreneur is more about persistence than anything else. Just be stubborn.
What year are you in school? Most of the Code you write as a Freshman is going to suck. You might not know it yet, but it does. Even if your code is the best in the class, it still probably sucks. Just keep hacking (and learning) and you will get better at it.
Blogs are free, both to produce, and to consume. That means the barrier to entry is low, and their are a lot of them. As a product, blogs are commodities. The difference between your blog, and most other blogs, is imperceptible to the average reader.
Think of it like tomatoes. If you grow a small plot of tomatoes in a community garden, what makes your tomatoes different than the one's at the supermarket? People know where the super market is. They don't know where your garden plot is. And even if they did, the only difference between yours and theirs is that you grew yours in a garden. What's the difference between your garden tomatoes and your neighbor's garden tomatoes? Most people don't know.
If you want people to read your blog you have to:
1. Make sure they find out about it
2. Make it very obvious why your blog is different from everyone else's, and why it's worth reading. "But I'm smart and I wrote it" is not an obvious reason, because no one knows who you are.
3. Build something people want. People have to want to read what you are writing. What need does your blog fill?
In any case, you should do 3 things:
1. Focus.
2. Relax.
3. Find your own path.
