Before you can play complex pieces, you need to master the basic elements of technique, similar to how percussionists practice simple rhythms repeatedly.

Going back to the fundamentals is crucial, as they impact everything you do, even in complex pieces, so it's okay to press pause and focus on them.

If someone points out that you need to work on your fundamentals, it may be time to pause your progression and address those essential skills.

Perfection and accuracy are crucial in mastering techniques, as they are built from simple blocks that must work well together.

You should aim to play a piece accurately and with musicality before moving on, possibly setting performance or recording goals to enhance your learning experience.

Making your technique modular helps in practicing effectively, allowing you to focus on specific skills needed for a piece. Practicing like Rafael Nadal, who focuses on repetitive drills, helps internalize techniques so that when it's time to perform, you don't have to think about it.

It's more important to focus on accuracy rather than strength when practicing guitar techniques.

Technique consists of many small building blocks; if one is missing, the entire performance can falter.

You can move on from a technique once you've achieved a certain level of control, but it's also important to revisit techniques as you progress, as you'll encounter new challenges and insights.
