Bro to bro- do not try entrepreneurship if you don't have a high tolerance for uncertainty. For long periods of time, you genuinely won’t know if you’re early, wrong, unlucky, or just stupid. You need to be cheap before you can afford not to be. Because raising money and burning it is easy. Building something people are willing to pay for is hard. You need high self esteem and a low ego and you've to be comfortable being wrong, looking stupid and changing your mind. Most importantly, learn how to lose without becoming a loser. Because you’re going to lose a lot- money, people, deals & time. Just don’t lose your ability to think clearly. And btw, don’t go looking for motivation. It is useless after a while. What you really need is stamina. Both physical & mental.
Nobody teaches men that life runs on game theory. Not as an abstract concept but literally how every negotiation, deal, and relationship plays out.
The first rule is whoever needs the outcome least has the power. It's why the guy who's desperate for the deal gets a worse price than the guy who can walk. It's why chasing money directly makes you worse at getting it and why people say yes to things they should say no to.
That's why leverage matters more than cash imo. Leverage is optionality. It's having enough going for you that you never have to take the first offer.
