How do I learn? Or rather what?

KK here's what's up:
I want to learn .NET development. I have limited experience from C++ and have been messing about with C# lately, making server/client apps, connecting to MySQL etc. Good times.

But I'm lost as to what the hell I'm supposed to do now. What am I supposed to learn? I'll be slowly grinding out the uhm, standard C# "library" :), but what do I do in the meantime? I'm perhaps leaving this too open, I guess I'm basically asking what I specifically should focus on to become a good programmer ready to go into a career as a programmer without a school diploma.

Also how does programming go down in the business world? Let's say for a .NET application with 10 or so programmers, how is the project managed, are there any good online documents on this?

Thanks in advance!

I would forget .NET and C# all together. You want to write code that is portable between platforms. You want to be able to make applications for the ICrap and Android mobile phones and tablets. You want to be able to port to linux.
Just like I would advise against ASP.NET and go with PHP.

Java is pretty damn good at server/client stuff, and portable. Can even compile from java byte code to platform specific if you want the speed boost.

While I do like C#, I would go with java instead.
