I'd image it would go something like this:
1. clean concrete, stucco, painted metals.
2. clean bricks and tiles.
3. clean wood floors and features.
4. marble, more complicated patterns. Still relatively clean.
5. More dynamic iterations. Cracked tiles, iregular bricks, dirt blending, damage blending.
6. Organic materials, dirt ground, cracked ground.
7. Organic materials +. Cliffs, leaves, moss, grass etc.

Fail. Learn. Redo
So. see it as a learning opportunity. Do the best you can, with whatever basic things you can do, then do more, challenge yourself, make it the best of your abilities. Rinse and repeat.
Every material breakdown I see posted with a million nodes feeding backwards and forwards across the graph makes me die a little inside.
As does every material that only covers 50cm of space - modern game maps are 5-10 pixels per cm tops. If you can't make an 8metre tile you're no use in production at all.
Fundamentally there are no complex materials, just lots of simple layers..
My first substance and my last, one year inbetween. If you wanna get good at something new, you're not going to be good in the beginning, that's only natural.
My best advice is try to create a variety of materials. Organic shapes, sci-fi walls, broken pottery - they all challenge you in different ways. Then after a while, get back to the same material and look at it critically. You can learn a lot from looking at your old work with new eyes!
Also like has been said, layering is one of the most important things when making substances. Being able to split a reference into sections is super important, and it will make the creation process easier. And like poopipe (...?) says here, a tidy graph is worth something in itself
