When I find myself becoming jealous of others, which at times is more than I care to admit, I tell myself this “their path is not my path”. Kind of like the grass isn’t always greener on the other side. For some people, they just know what it is that they want to do with their lives, as far as a career goes. For others, it feels like you’re just drifting. But a job doesn’t make you who out are. You make you.
A high paying job doesn’t mean that that person is more important than someone who has a job say at a grocery store. Every person is equally as important and is someone. Even when you die, you’ll still be someone. You’ll be someone’s child, someone’s friend, perhaps someone’s parent (if you have children), someone’s sibling (if you have them). And even if you never have children, even if you don’t find something you truly love doing.... you’ll still be someone, you’ll still be equally as important as the parent of 10 or the CEO of a company. Hopefully I’m making sense. You are important, and take baby steps. It doesn’t matter how many steps it takes to reach the goal.
Try making smaller goals, or narrowing down. Instead of “what do I want to do?”, try asking yourself “what do I Not want to do”. Then make a list of things that don’t interest you, things you dislike/hate.
Or you could always try what type of hobbies you like or things you enjoy. I love children, I love their big imaginations and the things they say. So I became a childcare provider.

Either way, small steps so you don’t overwhelm yourself. I know it’s not easy when you feel like the weight of the world in weighting you down on something society puts so much emphasis on. You are important, you are somebody!
