SECTION 7 — LEARNING STRATEGIES

The Spaced Repetition System​

For Technical Concepts​

Use Anki (spaced repetition flashcards):

Example cards:

Q: What is the CAP theorem?
A: Can't have Consistency, Availability, and
   Partition tolerance simultaneously

Q: What's the difference between vertical and horizontal scaling?
A: Vertical = bigger machine
   Horizontal = more machines

Q: What's eventual consistency?
A: System becomes consistent given enough time,
   but may be inconsistent temporarily

Strategy:
- Create cards while learning
- Review daily (10-15 min)
- Compounding knowledge

The Feynman Technique​

  1. Choose concept (e.g., “How React reconciliation works”)

  2. Teach it (write blog post or explain to junior)

  3. Identify gaps (where you struggled to explain)

  4. Review & simplify (fill gaps, simplify language)

  5. Repeat until you can explain to non-engineer

The 50/50 Learning Split​

50% Input (Learning)
- Reading
- Courses
- Videos

50% Output (Applying)
- Building
- Writing
- Teaching

Most engineers do 80% input, 20% output.

Top 1% engineers do 50/50 or even 40/60.

The Weekly Learning Routine​

Monday:
- Read 1 chapter of technical book (1 hour)

Tuesday:
- Watch 1 course module (1 hour)

Wednesday:
- Practice coding problems (1 hour)

Thursday:
- Read engineering blogs (30 min)
- Write notes/reflections (30 min)

Friday:
- Build side project (2 hours)

Weekend:
- Deep dive project work (4-6 hours)
- Write blog post (2 hours)

Total: ~12 hours/week

Consistency beats intensity.
