In my opinion, it really shouldn't matter about the difficulty of the sleight or trick. It's pretty dumb that people get discouraged by not learning it just because of its difficulty level. If you're really into this, just practice your butt off and be patient because it does take time into learning sleights. Even if it's the simplest sleight, you should put a lot of work into it and put every little detail into it. Most people regard this and just do it when they can "attempt" it when it doesn't even look good.
Just saying, it's more about your dedication towards learning and improving than the "level" of the sleight/trick.
