Yoga is never going to get easier.
The whole philosophy is that you do as much as you can, and then a bit more. Even if I get good enough to cross my ankles behind my neck, I'll always be trying to touch a spot that's just outside my reach.
Of course I could always make it easier by settling for what I can do already, but then I won't improve. And you know, the main reason I wanted it to get easier was so that I could feel I was improving.
