Always loved this advice from Steve Jobs, but it can be hard to put into practice in a startup.
From my own experience, I’ve found there is a strong temptation (and also external advice) to try many different things in trying to get traction.
From my experience meeting highly successful people, or whatever that means, meant deducing most of your interactions should have a straight no from you right away after listening attently, many times no eye contact is made (to make it more objectively perhaps). Then that "no" can be a blunt, almost out of place surprising no at the start "I don't like/see it", "not interested", "can't do that" etc. Which should quickly lead the conversation into solving your objections. Think of it as a figure of speech or a Socratic rhetoric. Once your petty or founded objections are resolved your "real no" may materialize as non-rhetoric. Remember, if you are the one saying yes or no it means you have some, if not all, leverage in that interaction.
Like I said, I've seen this from extremely rich, old money, people with whom I've interacted, so it's anecdotal and take it with a punch of salt. It's easier said than done anyway.
>That can’t make you money unless you’re a trust fund kid.
Yes, Jobs indeed comes from a very priveledged background that can afford to send their kid to college, have them drop out less than a year later, then send them on a 2 year soul searching journey before founding and crashing 2 startup businesses. And Buffet was a son of a congressman who bought stocks at 11 and land at 15 (I dont think either of those things are even legal o do today at those ages).
They very much were trust fund kids.
