O'Leary argues that about $5 million is all you truly need in the bank to be secure for life. The discipline is to get that first $5 million secured in your own name, put it in Treasury bills, and never touch the principal — spending only the interest. It's a goal big enough to push you yet not so large you stop working. He warns that many entrepreneurs forget to take anything off the table, keep rolling the dice, and end up with nothing when leverage or bad luck hits.
Origin
O'Leary set this goal for himself decades ago and has never touched the account, which has grown well past $5 million over the years. He rolls a block of T-bills as his security account and buys dinner with the interest, and now tells every entrepreneur to do the same on their way up.
Core principles
- 01Roughly $5 million is enough to be financially secure for the rest of your life.
- 02Secure that first $5 million in your own name and place it in Treasury bills.
- 03Never touch the principal — spend only the interest it throws off.
- 04The goal is big enough to push you but small enough that you'll keep working.
- 05Entrepreneurs who keep rolling every dollar back into the business risk ending with nothing when something goes wrong.
How to run it
- 1
Set the $5 million security target
Adopt $5 million secured in your own name as the goal — enough to make you and your family safe for life without making you stop working.
Pro tip Look at the balance on your phone every day and say 'I've achieved that' — it reinforces the discipline.
- 2
Park it in Treasury bills
Move the secured money into US Treasury bills. O'Leary notes gold is an alternative but has no yield, whereas T-bills throw off interest.
- 3
Never touch the principal
Roll the T-bills and leave the principal alone permanently. It's your protection if things go wrong.
Watch out If you keep rolling all the dice and take nothing out, one bad event can wipe you out entirely.
- 4
Live off the interest
Spend only the yield the T-bills generate — 'I buy dinner with the interest' — and keep working and building past that point.
In the wild
O'Leary set this goal decades ago, put the money in T-bills, and has never touched it; the balance has grown over the years and functions purely as his security floor while he keeps working and investing.
→ He remains permanently financially secure regardless of how any individual deal or business performs.
Common mistakes
Never taking chips off the table
Entrepreneurs who reinvest every dollar and never secure a floor can lose everything when excessive leverage or an external shock hits.
Dipping into the principal
Spending the principal instead of only the interest destroys the entire point of the untouchable safety account.
Is it for you?
Best for
Entrepreneurs approaching or past their first major liquidity who want a permanent safety floor.
Not ideal for
Very early founders with no surplus capital yet, for whom the priority is still building revenue.
