What would you actually be missing if you completely ignored what other people expect? Here's the thing: your friends might have figured their stuff out earlier, but that doesn't mean they actually know what they want - most of them only realize later that they were just meeting expectations. But at 30, you've got the advantage of having enough life experience to make real decisions, not just coast on autopilot.
Here's what might help: write down what gives you energy in your everyday life and what drains you - not the big existential questions, just small things. What tasks make you lose track of time? What do you ask people about? What do you do voluntarily when you can't be bothered with obligations? That often tells you more than any career test. The feeling of failure is real, but it's also a signal that something needs to change - not because you're running late, but because your gut is telling you that now is the right moment.
