Stuck.

You would not believe exactly how accurately your description of your feelings when learning to code match up with what others have experienced. This is an amazing read and definitely worth your time. Check out this blog post.

Now, as to what to do? There's really only a few things you can do. Keep practicing, keep learning, and keep trying! Quitting is never the answer.

Don't be afraid to post questions in the Community not just about how to do something, but about why it is done. As you have likely already noticed, the same concepts come up again and again like variables, loops, conditionals, logical operators. It's (mostly) only the how we use them that changes from language to language. But the "big picture" ideas are very much the same!

Hope this helps and hang in there!

I have a same feeling but what I feel like is I only know what the teachers showed me. It depends on the course but lets say the node.js kept me so messed up that I left it for a long time

Nils, you're not alone. I've experienced it in most of the courses I've tried. You're cruising along at a nice pace, but at some point... vrroooomm! they shoot you off into something advanced and suddenly you can barely keep your head above water. You're left wondering if there was some intermediate step you missed.

In addition to the blog post Jennifer referred to, you can find a similar discussion on this reddit post. Something I read and found encouraging, when I was at a low point, like you are now. I kind of liked this guy's observation that often times "it's not you, it's them". A lot of the people teaching tech courses online are very skilled at at the technology they're teaching, but not very skilled at teaching, in and of itself. (Note, I'm not singling out or picking on Treehouse here, because the phenomenon is everywhere) .
