Key Lessons from the Journey

The most important insights gained through this transformative experience

Process Over Outcome

Focusing on consistent, high-quality process rather than obsessing over specific results led to better outcomes and reduced anxiety.

Time Investment Pays Off

The 3-month intensive at Recurse Center was scary but created the foundation for everything that followed. Sometimes you need to take calculated risks.

Network is Everything

Informational interviews and genuine relationship building provided insights and opportunities that applications alone never could.

Failure is Feedback

The first application process that ended in rejection was devastating but provided invaluable insights about gaps in my preparation.

Skill Stacking Works

Combining Rust development, open source contributions, and research experience created a unique profile that stood out from other candidates.

Persistence Beats Perfection

Consistent, focused effort over 18 months eventually led to success, even when individual attempts didn't work out as planned.
