Study better
Keep a decision journal
Capture the reasoning you want to recall under pressure.
Understand the problem
Record the constraint, options, chosen trade-off, and what evidence would change the decision. Review recurring weaknesses weekly instead of collecting unstructured links.
Make it concrete
“Queue workers are bounded because the database connection pool is the bottleneck.”
Trade-offs and pitfalls
Detailed notes help only if you revisit and apply them.
Check your understanding
Write one decision you reversed after a prototype or production observation.
