What If Claude Could Learn From Your Best Mentor?

Most people don't have access to a great mentor. The ones who do know how rare it is — someone who's already made the mistakes you're about to make and can see the gap between where you are and where you think you are. I don't have that person. But I figured out a way to get something surprisingly close to it, and it costs nothing.

The idea is this: take everything a specific expert has ever written or said publicly — their books, their interviews, their threads, their frameworks — and feed enough of it into Claude that it can start to reason the way they do. Not to impersonate them. To extract how they think about problems and use that as a lens.

I did this with a few people whose thinking I really respect. I pulled long-form interviews, key essays, and core frameworks. I pasted them into a Claude session with a single instruction: 'Study how this person thinks about business and growth. When I ask you questions, respond using their frameworks, their priorities, and their way of cutting through noise — not generic advice.'

What comes back isn't the actual person. But it's surprisingly useful as a filter. When I'm about to make a decision, I can ask Claude to evaluate it through that person's lens and get a response that actually applies their frameworks — not just a surface-level summary.

The real unlock is using it for accountability. When I want to know if an idea is weak, I ask Claude to critique it through that person's lens. It's harsh in the right ways. It asks the questions I was hoping nobody would ask. That's the thing about a real mentor — they don't let you get away with the half-baked version.

This works best with people who have written a lot in their own voice — where their actual reasoning process is visible, not just their conclusions. The more raw material you give Claude, the more accurate the pattern becomes. And once it's set up, every question you ask gets filtered through a level of thinking that would have taken you years to develop on your own.
