One engine is to have underlying earnings (or cash flow or book value or whatever the relevant metric is for the business) grow at a high rate for a long time. The second engine is to get that valuation lift.
The ideal candidate would have both of these twin engines working for you. But we live in a world that is less than ideal. And so if you get a great business that can compound for a very long time at a high rate, I wouldn’t chafe too much at paying up a bit.
Invest in a business that makes things people really want/need.
