Wait, I thought xcross was intuitive. Why would you need to learn it?
Instead of focusing on getting faster you should be doing things that will get you better in the long run. IMO the most important thing (besides knowing basic finger tricks) is to understand how the cube works. Try out different methods and work on blockbuilding. Watch how certain moves effect the pieces. An xcross shouldn't have an algorithmic approach to it. I do xcrosses at least 40% of my solves and I have never watched a tutorial on it. It takes some getting used to but eventually it becomes almost second nature. I still can't do FB in inspection but that's just because I haven't put enough time into it.
The ultimate goal of a speedcuber shouldn't be to become the fastest (number one), that's a meaningless pursuit and it's impossible for the average person. You should instead be trying to learn as you improve trying to see how one thing correlates to another. Understand why this does that. It's fine to have help or advice, go ahead and watch a video if you think it will help you discern certain techniques but your answer for every problem shouldn't be to go and watch a Jperm video. That destroys the intuitive process and closes and padlocks a lot of doors that you'll have to struggle with later. I would actually (this is a very unpopular opinion and will probably make this a "meh" post because 14 year olds don't like it when you aren't a cultie) highly advice against watching Jperm who I think destroys a lot of creativity. A lot of people when answering anothers question will just tell you to watch Jperm's video and I cringe. Every. Single. Time.
Jperm isn't the all knowledgeable cuber most think he is he makes videos with very little idea of what he's talking about or makes it so methodical that you gain absolutely no further knowledge from it, but at least you know how to do Roux now amiright. Try to figure it out yourself and if you think a video will help watch one that teaches you how to get on your feet and do it yourself. The Rubik's cube is a puzzle, not some video game easter egg. Learn from it don't have others do it for you.
