Well,… my fave post grad course was Bankruptcy. It was insolvency after insolvency after insolvency and in a way also survivorship bias, but I digress — like Poor Charlie (RIP) used to say: find out where you are going to die and make sure never to go there.
And if you happen to end up there any way, make sure you die properly and in grace. Aka, manage your bankruptcy properly, without any shenenigans and refusal to accept the inevitable.
