I was the same as you for a few minutes - I was demotivated and when I found out what was behind it I thought "huh I never learned this and I'm not sure how I would have ever learned this" and felt a little bit defeated. But then I read a little bit on the subreddit, read the wiki on CRT, put together a solution and moved on. It's meant to be a bit of fun, if you have to skip one challenge (or cut a couple corners) it's no big deal - you can always come back to it later :) It can be demotivating if you check the number of people who solved it quicker you, but just pretend they all cheated off one really really smart person and you'll feel much better :D
