The real question here isn't whether your business idea is good — it's whether you can tolerate the identity shift from employee to founder before revenue arrives. Your stated values of autonomy and creative freedom are directly strangled by your current role. Every month you delay, you're paying an invisible tax in the form of accumulated resentment — and that tax will eventually cost you more than the financial risk of leaving. The reversibility calculus matters here: starting a business is far more reversible than most people believe. Skills don't disappear, networks survive, and industries rehire. What is irreversible is spending another two years watching the window close on a market opportunity. Your biggest fear — running out of savings — deserves honest math, not emotional treatment. With 9 months runway and a 3-month sales cycle, you have exactly two full attempts before you must reassess. That's not catastrophic; that's a defined experiment. The hidden assumption doing the most damage: you believe you need certainty before you begin. You don't. You need a reversible first step — and you already know what it is.
