Spending years building a business for someone else (even a parent) while being undercompensated is a powerful training ground. It forces a level of conviction, humility, and delayed gratification that can lead to explosive growth once you start your own venture.

The ability to identify opportunities, prototype cheap experiments, validate ideas, and scale is becoming the most crucial skill set. Both corporations and startups will need people with this mindset to navigate constant AI-driven change.

The skills acquired while running a side business—from project management to client communication—directly translate into being a more effective and business-aware engineer in a full-time role. This experience provides a holistic perspective that benefits the primary employer.
