2nd week at my first job after I got my papers and what am I doing?

Background:
I followed a course of three years where all we learnt was web development with php and javascript. I of course wanted more and spend hours after school learning as much as a could without any help from others.

About the course:
We learn to tinker with code (php, javascript).
There was never a mention of design patterns.
We never got to know about TDD (test driven development).

Now:
Got the papers, found a job as a c# junior development and am currently working on a C# .NET web app using azure cloud and high standards using unit tests to provide a product for the awesome company I work at which should generate a stable income.

Tldr;
Hard work pays off.
