Junior programmers too often make the mistake of thinking the code they write is intended for consumption by the machine.
Coding is an exercise in communication. Either to your future self, or some other schmuck down the line who inherits your work.
When I practice the craft, I want to make sure years down the line when I inevitably need to crack the code back open again, I'll understand what's going on. When you solve a problem, create a framework, build a system... there's context you construct in your head as you work the project or needle out the shape of the solution. Strive to clearly convey intent (with a minimum of cognitive load), and where things get more complicated, make it as painless as possible for the next person to take the context that was in your head and reconstruct it in their own. Taking the patterns in your brain and recreating them in someone else's brain is in fact the essence of communication. In practice, this could mean including meaningful inline comments or accompanying documentation (eg. approach summary, drawings, flowcharts, state change diagrams, etc). Whatever means you have to efficiently achieve that aim. If it helps, think of yourself as a teacher trying to teach a student how your invention works.
