"Make skill easy and make strength hard."

Once you understand this perspective it can make things much simpler for categorizing your training making progress.
Are you training in skill or strength?

The goal of skill training is to become better at the skill. The intention should be to perform the skill with high precision using minimal effort. Ultimately this will be accomplished through not only proper technique, but also through mindset and perspective. As you get better, ths skill should take less and less effort to complete.
How many times have you seen someone do a cool move and thought, "they make it look easy". That's the point of skill work: make it easy. Relax. Own it. Put the skill in your pocket so you can pull it out at any time. Make it look easy even in the worst possible conditions.That's the goal of skill work.

The goal of strength training(or any other attribute) is to increase your physical capacity. The intent is to make the movement difficult to complete so that you can create adaptation in your body. When the same movement becomes easier, the exercise should be modified to increase the difficulty and maintain the level of challenge. This is usually accomplished by adding reps, modifying tempo, increasing load, or decreasing leverage.
Make strength hard so that you're putting in effort and allowing yourself to build from it.

Remember, this is about perspective and classification of training. I can take any movement and view it as a strength or a skill, and that will change how I train.
Think about whether the movement you are performing should be easy or difficult, and that will change how you perform it.

Sometimes the two concepts can overlap as well. Take the handstand for example: though it is a skill, there is still a base level of strength required to perform it as a skill. That means that some students may have to treat handstands as a strength move with the intent to graduate it to a skill.
Some movements are combinations of strength and skill, which means sometimes in training you can separate the technical work from the physical adaptation work.

Anyway, it's the concept that's important. Make skill easy and make strength hard. Figure out what you're training and adapt your perspective, movements, and mindset accordingly.
