opportunity cost

Set an absurdly high hourly rate and use it to cut low-value tasks from your life.

Every decision should be evaluated at the last unit, not the average

Debt interest is a tax today, not a problem for grandchildren

Trade benefits both parties even when one is better at producing everything

Evaluate opportunities by multiplying profit potential by time freedom rather than revenue alone

The biggest risk is not failure but spending your time on things that succeed but do not matter

Calculate the hidden catastrophic cost of doing nothing to overcome status quo bias

Measure the hidden price of not deciding to decide

Reveal the invisible costs hiding behind appealing institutional choices

Compare options against each other, never against zero

Knowing when to fold is the highest-leverage decision skill

If you're not saying 'Hell yeah!' to an opportunity, say no

Evaluate every purchase by what the money could earn if invested instead

Set an ambitious personal price to ruthlessly protect your time and outsource everything below it

We chase options we do not need because losing any possibility feels like dying
