  • D'Avella values this intense challenge so highly he is actively paying to repeat similar training for national qualifications.

The Method: Total Immersion for Hyper-Growth

Matt D'Avella's approach to earning a Taekwondo black belt in just 90 days was total immersion. He committed completely to the goal. As D'Avella puts it, “I make it a challenge so that I can devote my whole life to it.”

This wasn't a casual hobby. He sought out Grandmaster Simon Ray, a top martial artist, who then pushed him rigorously. The aim was not merely to learn moves, but to internalize the discipline and mental toughness of a martial art from scratch.

Achieving the goal meant putting his “body through a lot,” enduring extreme physical and mental demands daily. The Grandmaster's belief was central. D'Avella notes Ray “did what most instructors would have never done, which is believe in me and push me to try and actually get a black belt in 90 days.”

This method uses a compressed timeline and an all-in mindset to force a discontinuous leap in skill and self-identity. It's about intense focus over a short, defined period to trigger a rapid growth spurt.

Where This Breaks Down

D'Avella's method is expensive, both in time and resources. He had the flexibility to “devote [his] whole life to it” for three months. Most founders cannot drop everything for that period.

This approach also demands access to a Grandmaster Simon Ray – an elite mentor willing to take on an unconventional, hyper-accelerated challenge. Such mentors are rare. Finding one who will take you on for such a task is even rarer.

The psychological cost is also high. This isn't about incremental growth. It's about breaking through personal limits under extreme pressure. Not everyone thrives in that environment; many would burn out or quit.

The "black belt" here serves as a proxy for skill and mental grit. The direct transferability to, say, building an app or scaling a team in 90 days is not guaranteed. The principle applies, but the specific application might vary greatly.

What to Do With This

Identify one skill or area of personal development you genuinely want to master in the next 60-90 days. This isn't about improvement; it's about achieving a level that would represent a "before and after" moment for your capabilities. Next, ruthlessly clear your calendar of all non-essential activities for that period. Find a mentor, even if for a short sprint, who you pay to hold you to an absurdly high standard. This week, pick the skill and begin the mentor search.
