I suppose I could be more specific in case someone else finds it helpful.
I am currently pursuing a BS in Comp Sci at an obscure online university. I decided to supplement this with classes from Udacity. However, I found myself becoming addicted to the little 'correct' sign when you get an answer right. I found myself going mindlessly through the courses as if merely having taken it would make me better. I've since slowed down, making sure to internalize the information, and I've allocated much more time into building my portfolio so I can show future employers something more substantive than an easily-fakeable certificate.
I also changed a strategy from googling "How do I get into [x]" with doing actual research about what x involves and how best to get there from where I am now. In my experience, the former approach provides little useful information.
Just to make sure, by "building portfolio" you mean making computer programs, or what? What kind of programs?
