Not to take a personally guaranteed bank loan to start a startup. Ever. In any situation. No matter how risky they think it is. Ever. No matter what. Just not to. Because I love my family. Once I'm convinced they understand that, I'd teach them how to model the loan itself - how much they would need to repay for how long etc'. I wouldn't bother to teach them how to model the bank's risk because they shouldn't care, they ask the bank and get an of|er in the form of an interest rate. But of course, no bank would finance an early stage startup with a non-personally-guaranteed loan, so this is all irrelevant because I trust them to never ever finance a startup with a personally guaranteed loan so there is nothing to model here.
