I just shipped something I’ve been building for the last 18 months. It’s not perfect, it’s not a „unicorn,“ but it’s *mine*—and I’m proud of it. That said, quitting my job to do this was the hardest decision I’ve ever made. Here are 5 things I wish I knew before taking the leap—none of them are what you usually hear.

1/ Your runway isn’t just your savings—it’s your *mental* runway. I calculated I had 24 months of burn. But I didn’t account for the 6 months I’d spend paralyzed by doubt, or the 3 months I’d lose to a family emergency. Stress doesn’t care about your spreadsheet.

2/ The „hustle“ culture lied to you. I thought I’d be most productive working 80-hour weeks. Instead, I burned out in 6 months. The real unlock? Ruthless prioritization. I now work 40 hours a week, but *every* hour is focused. Output > hours logged. Sleep is a competitive advantage.

3/ Your network is smaller than you think. I had 10,000 followers and a „strong“ LinkedIn presence. When I launched, *maybe* 50 people cared. The people who *actually* showed up? The 20 I’d built real relationships with over years—not the ones who liked my posts. Depth > reach. Always.

4/ The market doesn’t care about your „why.“ I built something I *personally* needed, convinced it’d resonate. It didn’t. What saved me? Talking to strangers—*actual* potential users—not friends who „love the idea.“ Your vision is a hypothesis. Test it like one.

5/ You will *hate* being „the boss.“ I thought I’d love calling the shots. Instead, I miss having a team to *share* the load. The loneliness of leadership isn’t talked about enough. You’re the one who has to make the call—even when you have no idea what the right answer is. Find your people. You’ll need them.

If you’re thinking about quitting your job to start something: do it. But go in with your eyes open. It’s the hardest thing I’ve ever done—and also the most rewarding. Just don’t expect it to look anything like the highlight reels you see online. (And if you found this helpful, I’d love to hear which point resonated most. DMs open.)
