Personal Growth / Zara Zhang Rui

Zara Zhang Zala / PM & VC Career Trajectory + Computer History Museum Docent

Zara’s full career reflections across GGV (VC)/ ByteDance (6 years in product marketing)/ AI indie development, plus her hands-on experience as a volunteer docent at the Computer History Museum. **Core arguments**: Not planning takes you further than planning (every career turn was triggered by her work); PMF is not a marketing problem, it is a product problem; Always-last-day mindset; **Learn in public — output forces input** (proven by memorizing an 8,000-word English script and leading more than a dozen tours). Also includes counterintuitive views on entrepreneurship (why she does not want to start a company) and storytelling lessons from the Vegas/Mob/Neon museums.
