Every video is a full walk-through of the math, not a teaser for a call. The channel is the free version of the work.
Why this exists
The best retirement advice kept getting buried.
Most of what you find about retirement is written for someone with a very different balance sheet. Or it’s a sales pitch wearing a cardigan. The genuinely useful part gets lost in the middle, and that’s the part that changes what you pay and what you get to spend.
So I started publishing it. The same planning work I do for families at Define Financial, explained in plain English, with the actual numbers on screen.

What actually happens
One decision. Six systems that react to it.
A withdrawal, a conversion, a gift. Any one of them moves two numbers, and those two numbers are wired into six different parts of your bill. That’s the part a calculator can’t see. It’s also most of the work.

45 long-form breakdowns. Every one has its own page here, with what it covers, where to go next, and the written guides behind it.
