When you learn a new skill, you can expect the learning rate to be pretty steep and fairly intense. You may have a natural basic talent or interest in it, but to improve you'll have to do a lot of work and practice.
You might find yourself buried in books trying to absorb as much as you can. Or endlessly watching tutorials and videos on how to do it by experts. You attend workshops, courses, one-on-one teaching. During this time you can imagine that there'll be a gap between what you can achieve and what you want to achieve.
I'd imagine, that all of this concentrated effort will feel challenging and hard. It may feel like you'll never get the hang of it, or never meet mastery level.
And then... All of a sudden, it eases off. Things start to fall into place, and you're finding it easy. Maybe even simple. But does that mean you're doing it wrong now? Have you lost the path of the challenge? Have you taken the wrong road and are no longer forging forwards?
It's like you've just been climbing part of a mountain and the road has started to level off a bit. It's started to feel easy. And you catch yourself. Easy? Climbing a mountain isn't meant to feel easy. Should you push harder now? Try and regain that feeling of challenge? Or should you accept that it's a momentary slackening in the pressure, and you can catch your breath. Even enjoy it, somehow.
Perhaps it's only a matter of perspective. It's not necessarily easy, it just feels easier. Easier than what you've just gone through. The learning curve has plateaued a bit and this is your cue to put what you've learnt into practice. Recap a little; check you've understood it all.
So perhaps, instead of using the metric of hard or easy, maybe it's time to see if what you've learnt can be used and if there are any gaps left that you need to fill.
