You can have a life and still feel like you're waiting for it to begin.
Lately I've been wondering whether one of the worst feelings isn't failure, but the feeling that your life never really began.
Not that nothing has happened, but that everyone else seems to have figured something out that you somehow missed, while you're still waiting for the moment when everything finally starts to click. You can have a job, relationships, hobbies - even moments of happiness - and still feel like you're somehow watching everyone else's story from the sidelines.
I don't know if that's reality or just the way comparison distorts our perception. Maybe everyone secretly feels like they're behind. Maybe we only ever see the polished version of other people's lives. Or maybe every generation has felt this way, and we're just the latest people to mistake a universal feeling for a uniquely modern one.
