People have widely different software engineering skills.  I think it's very common in this business for the most skilled developers to be 10-15 times faster than less skilled developers.  It's just the nature of what we do.  If you can see the underlying design and truly understand how a piece of software works, you can find and fix problems much faster than somebody who doesn't get the deeper picture.

As to how to get better at that?  Generally it takes years of education and study.  There's no quick fix.

If this site seems too complex for you, I'm not sure you're really in the right field?  My daughter learned from this site last year without any help and she's only 11.

I'd say give it another look and see if you can figure it out.

Doug, please consider that English might not be his native language. Also, for a site like that, a difference in culture might get in the way.
I see some Maven text boxes there.
Please don't confuse

with
