The problem isn't routine itself, but that you're getting pulled into it passively. A steady paycheck and a fed family - that's genuinely the foundation, but a foundation for something. If for five years you come home and just consume (cook, watch stuff, sleep), then yeah, life passes you by. But if in those same five years you've learned a language, started doing something, picked up a skill with your hands or your head - that's completely different. Meaning doesn't come from monotony itself; it comes from what you add to the monotony.
Here's the thing nobody talks about enough: people often expect meaning to just appear, like you need to meditate properly on your routine or shift your perspective on it. That's an illusion. You can shift your perspective all you want, but if nothing actually changes in your life after work, that sense of stagnation won't go away. It's real.
Try being honest with yourself: is there even one area right now where you're actually moving forward? Not "I'm planning to start" - something you're genuinely developing right now? If not, it's not about finding meaning in routine; it's about adding something that makes the routine stop being hollow. Even something small: upskill in your field, start a project, get better at cooking, take fitness seriously. Stability keeps you from falling, but it doesn't lift you up on its own.
