Day Summary

Today, I breezed through the first part (the remainder of the structs chapter), went to the coding part - guided coding, then recreate from memory—and then back to reading. I started on the enums chapter relatively motivated, which quickly turned into boredom because my brain kept telling me, Is this important? Do we really need this? Can we do something else? And that was the trigger for me to realize: ah, I have not given my brain sufficient reason to consume the vast amount of details that is presented on these pages.

So I went back to Chattopadhyay, pasted the whole chapter there, and told her to create a katha that encompasses all the concepts that are introduced. It did give me one. It's a giant one, and I started typing it out. I'm still not done typing it, but that is the whole concept. You notice your brain, and it feels like a struggle to concentrate, which doesn't tell you that you're not trying hard enough. It's telling you you don't have a reason—like your brain doesn't have a reason. It just needs a reason.

And so you go back and create the reason. You switch from theoretical to practical. You type it out. You try to understand what you typed. And then your brain realizes, Huh, this seems strange. I don't understand what happens there or why I'm doing this. And now it is worth the energy investment to read thoroughly through the details, and that's when reading becomes effortless again and recall becomes maximized.

• Active reading (40m, +13 pages): p.132→145 — wrapped struct methods, began enums.
• Guided coding (15m): struct methods.
• From memory (15m): recreated struct methods while recording.
• Guided coding (20m): started an enums “monster” kata; in progress.
• Execution win: completed the full 90 minutes first thing (DQF).

Context

• Followed Daily Quest First: coffee → start immediately → finish 90m before any detours.
• When enums began to feel boring, you gave the brain a reason: requested a comprehensive kata and started typing it for muscle memory.
• Nice bonus: tomorrow starts with coding (finish the kata), then read back with fresh context.

Reading

Two sessions:

1. 20m (p.132→139, +7 pages): reviewed/closed struct methods.
2. 20m (p.139→145, +6 pages): into enums; paused when engagement dipped.

Total: 40m, +13 pages.

Coding Practice

• Guided — Struct methods (15m): define methods, call them, confirm outputs.
• From memory — Struct methods (15m): rebuilt the same patterns without peeking (recorded).
• Guided — Enums kata (20m): comprehensive exercise covering variant forms and match; still typing it out.

Reflection

• DQF works. Securing the 90m early makes the day a win even if later execution drifts.
• Purpose beats boredom. A concrete kata restored focus when the chapter felt dull.
• Tomorrow: code first (finish kata), then re-read to clear any confusion, then a full from-memory rebuild.

Key Learning

• Structs ≈ data classes: clean, JSON-ish shapes; derive traits for ergonomics (#[derive(Debug)], etc.).

• Methods & receivers:

  • &self to read, &mut self to mutate, self to consume (move) the instance.
  • Passing self by value inside a method means you won’t have access to that instance afterward.

• Enums: central to Rust; pair naturally with match. Building an end-to-end kata helps cement real-world usage.

Total Time Spent

• Reading: 40m
• Coding: 50m (15m structs guided + 15m from-memory + 20m enums guided)
• Daily total: 90m

PCT (Project Cumulative Time): 11h39m (prev. 10h09m + 1h30m)
