The transition to a public company drastically changes a PM's role. Every initiative, including experiments, must be backed by data and tied to a clear return on investment. The "build for fun" or "hackathon project" mindset disappears, replaced by rigorous financial justification and frugality.

Don't commit to a rigid career plan. Instead, treat your career like a product. Run small-scale experiments or 'MVPs'—like a 20% project, a volunteer role, or a teaching gig—to test your interest and aptitude for new skills before making a full commitment, then iterate based on the results.

To overcome analysis paralysis from a previous failure, a 48-hour deadline was set to launch a new business and earn $1 in revenue. This extreme constraint forced rapid action, leading to quick learning in e-commerce, dropshipping, and online payments, proving more valuable than months of planning.

In a corporate setting, a PM might build a feature because an executive wants it. As a solopreneur, you personally absorb all financial and time costs. This forces a raw, unfiltered evaluation of business viability and opportunity cost for every decision, a muscle often atrophied in large organizations.

Sundial founder Julie Zhu intentionally avoids hiring product managers. This constraint forces engineers to take full ownership of the product definition and user value, preventing them from delegating critical product thinking and developing a stronger sense of customer empathy.

To overcome the paralysis of perfectionism, create systems that force action. Use techniques like 'time boxing' with hard deadlines, creating public accountability by pre-announcing launches, and generating financial stakes by pre-selling offers. These functions make backing out more difficult and uncomfortable than moving forward.

Building your own product forces you to confront technical realities like database migrations and architectural trade-offs. This firsthand experience provides deep empathy for engineering challenges, which in turn builds crucial credibility and improves collaboration with development teams.

When you're the only resource, you must be ruthless. You only build what is absolutely necessary to solve your own immediate problems. This eliminates stakeholder noise and "nice-to-have" features, teaching the purest form of MVP-driven prioritization where every feature must be critical.

When you're the sole decision-maker on a personal project, you never learn to influence without authority or manage stakeholders. This creates a significant skill gap because you have no one to push back, challenge your assumptions, or force you to justify your decisions, which are core PM competencies.
