“I have one big idea and limited savings. Play it safe or bet on it?”
First, what's the evidence the window is open now? I left Harvard because microcomputers wouldn't wait, but I also kept enough cash for a year of payroll, so it wasn't reckless. Quantify it. What's the market size, your burn rate, your months of runway? If the numbers say the opportunity is real and timed, bet, and measure weekly so you're not fooling yourself.
