I suggest you start at least thinking about the basic skills needed by working developers. My experience with new graduates at our company is that, despite having studied "computer science" for a number of years, there are often gaping holes in their basic, practical software development technique, such as:

• Always use a revision control system.
• Use a single-step automated build.
• Avoid duplication (DRY).
• Descriptive, explanatory, consistent and regular names.
• Useful commenting and documentation.
• Design the module's interface first.
• Sound domain abstractions.
• Wise program decomposition.
• Encapsulation.
• Highly cohesive, loosely coupled modules.
• Minimize the exposure of implementation details.
• Minimize the scope of variables, pragmas, etc.
• Write components that are testable in isolation.
• Write the test cases before you write the code.
• Add new test cases before you start debugging.
• Establish a rational error handling policy and follow it strictly.
• "Always code as if the guy who ends up maintaining your code will be a violent psychopath who knows where you live" (Damian Conway)

Many years ago, I was lucky enough to meet Bjarne Stroustrup. I remember him telling me that "you can't learn to ride a bicycle by a correspondence course". That is, becoming a good programmer takes practice, lots of practice. So you will need to find a little project to develop, to practice many of the techniques above. See also code kata.
