Structure: Structure is mainly the context, background, and organization of knowledge. It helps point you to what you need to pay attention to. It also lists out the different sub-categories or sub-skills within the skill. Depending on the breadth of the skill you may have many sub-skills if you choose a broad skill like writing, or few if you choose a narrow/specific skill like social media writing for finance executives looking to build personal brand online.
Technique: Techniques are the meat where people often focus the most. It is the what / who / when / how. Techniques are mostly rule based, and can be complex. However, diving straight into techniques when just starting out could be misleading as you haven't figured out all the components.
Resource: Resources play a much bigger role than most people think. Resources can be both public, and private. Knowing where to find valuable resources when you need them is the biggest differentiator between an experienced and a rookie. For a programmer, this might be the Github. For a designer, this might be Canva. And the ultimate goal is to build a private resource pool that you own.
The three parts reinforce on each other. For anybody looking to learn a new skill, this could be a useful framework to have before you dive - especially in the age of AI. You can prompt these to ChatGPT or Claude and let it teach and guide you each step, greatly reducing the time of learning.
