Four PM growth lessons from a Silicon Valley mentor

Executive overview

Most PMs default to maximising output — reading every email, closing every task — until the workload overwhelms them. The real shift is moving from judging yourself by what you can do to judging yourself by what you choose to do.

Four lessons separate PMs who plateau from those who compound growth across their careers.

The area of greatest professional growth is always the thing you emotionally shy away from.

Quality over speed at the start

• No one remembers how long the first shipped thing took — only how good it was.
• Early-career PMs focus too much on the product and not enough on the people around them.
• Ask junior PMs: "What does your engineering lead think? What does your designer think?" — the goal is to understand how they process others' input, not just collect opinions.
• Great products emerge from compromise and discussion, not solo vision.
• Strong opinions held loosely — updating when new information arrives — is the critical skill.

The mid-career trap: consensus without conviction

• Mid-level PMs learn collaboration and consensus-building, then stall.
• The missing move: knowing when to spend accumulated credibility to drive the team up the hill that matters.
• Collaboration is a tool, not the goal.

Choosing what not to do

• Early-career PMs treat work like a rising tide — they try to stay above it by doing more.
• The transition: learn to breathe underwater. The water is the work you won't do.
• Some tasks you could do, some you should do — you skip them because higher-priority work exists.
• Once PMs make this shift, visible anxiety recedes; they own their choices rather than their capacity.
• In startups, outcomes are determined by choices, not capabilities.

Eating the spike

• There is always one thing being avoided — a difficult conversation, a broken relationship, an uncomfortable decision.
• Eat the spike: go straight at the hardest thing first.
• Example: a stalled working relationship with a close counterpart. Every workaround failed. Dedicating a month to fixing it directly solved what months of avoidance could not.
• As soon as the spike is chosen, it gets easier.
• The things you shy away from emotionally are where growth lives — that's precisely why growth is there.

Managing senior PMs: allow small mistakes

• When you are skilled, the instinct is to fix mistakes for the people you manage.
• Senior PMs should instead identify what small mistakes their reports are making — and allow them.
• Controlled mistakes are the fastest learning path.

The Facebook RPM programme insight

• Facebook's rotational PM programme ran 12-month cohorts across consumer and non-consumer rotations.
• Key design decision: RPM managers were judged on PM growth, not project output.
• Result: when managers focused solely on developing people, business output also increased.
• Early-career PMs with dedicated growth-focused managers outperform those whose managers split attention.

Curating your own work life

• Burnout is often treated as a signal to make a big change — new job, new team, new career.
• Multiple small changes compound to large impact without disruption.
• Audit your 10 meetings: identify which energise and which drain.
• Halve the frequency of draining ones; double the energising ones.
• Deliberate, incremental curation — not wholesale reinvention — restores excitement and agency.
