Anyone who imagines that leaving a job they've had for years or decades and starting their own business based on their "passion" is going to be anything other than a grueling gauntlet of towering expenses, nightmarishly long days and sleepless nights, unforeseen challenges and unimaginable pressure, where they now have half a dozen jobs including CEO, CTO, CMO, COO, CFO, and janitor, for years before light appears at the end of the tunnel, and imagines they'll get to "keep the income generated for themselves", is in for a great awakening indeed ;)

Still go for it, of course, just....get ready
