Don't make this an either-or choice where you're forcing yourself to pick between them right now. That's what trips people up - they think it's either quit tomorrow or stay trapped forever, when there's a ton of middle ground you haven't explored yet.
What actually matters is whether you can build toward creative writing without nuking your stability first. Can you start freelancing nights and weekends while keeping your job and health insurance? I know that sounds like the grind people complain about, but it's how you actually test whether the passion holds up under real conditions. Some folks realize after a few months of doing their dream work in stolen hours that it's not as fulfilling when it's *all* you have to count on - the pressure flips the whole dynamic. Others discover they genuinely love it even when tired and keep building momentum. Either way, you get data instead of gambling.
The part that matters most isn't happiness versus security - it's that money stress and creative fulfillment aren't actually opposites. Chronic money stress absolutely kills your ability to do good creative work. But so does forcing yourself into work you resent just for the paycheck. The real question is whether you can bridge that gap gradually instead of jumping. Keep the insurance, keep a baseline income, test the writing work seriously for six months or a year, and *then* decide if you're ready to make the bigger shift. You'll know way more about what you actually want by then, and you won't have blown up your stability while figuring it out.
