# Productivity
All Productivity notes →Building Career Capital
Building rare and valuable skills before chasing passion — the asset that actually buys career flexibility later.
Portfolio Building
Compounding visible proof of skill — writing, OSS, a portfolio site — into leverage for the next role, instead of leaving it undocumented.
Building Your Personal Brand
A consistent public presence anchored to real work, so opportunities arrive inbound instead of requiring cold outreach every time.
Networking Systems
Treating professional relationships as a maintained system — a standing cadence, not a burst of activity right before a job search.
3 — Interview Preparation Systems
The tracking and cadence layer around interview prep — see System Design and Data Structures & Algorithms for the curriculum itself, which this book points to rather than duplicates.
4 — Continuous Skill Development
Budgeting deliberate time for skills that won't pay off for a year against the constant pull of work that pays off this week.
