Three interesting part of the discussion: (1) The opportunity cost to the founder of taking early liquidity: If a founder cashes out 10% of their position for $500k @ $25M Series A valuation, that de-risks a lot of their personal life. But when the startup ends up selling for $250M, that $500k of 'early' selling would have been worth $5M (less any dilution between rounds) - hard not to regret the choice in that case…
if you ask you mom or dad, whichever believes in you, they have enough money to fund your dreams (if you care enough to ask) of joining or starting a startup to become an (x) CEO/salesman/builder/marketer/whatever for whatever you want to build, and that includes signing onto some startup that won't pay you a living wage until it fail-exists for $5 million and everyone goes to burning man/Berlin/ibiza on the founders dime (including rent for everyone N months).
