understanding is the first step.
But I agree... it doesn't mean you can fix it. If you understood that a table fell apart because the screws came off, that's good.. but you'd also need the tools to fix it.
If you didn't happen to have those tools, or the knowledge how to use the tools... you'd have to find someone to lend you the tools and/or show you how to use them.

Keep trying,... keep trying to figure things out. And if you cant figure it out on your own, try to search out those "tools" by contacting other people who might be able to help you

keep going... and keep posting...
