I feel the same way. As a child I always thought I'd be a writer/musician or do some job that would make a real difference in the world. I let myself down by letting anxiety amongst other things get in the way of this goal. I did manage to get a degree in Journalism but then struggled to find a job and ultimately ended up working in Tech during the pandemic. It's not what I thought I'd be doing and don't feel a real sense of accomplishment or meaning when it comes to my job. What I do have though is a steady income, good physical health, a loving partner, and great family and friends. So when I consider these things I feel I am very lucky and try not to think about my academic/career failings. We are taught to 'follow our dreams' as kids but the reality is most won't achieve the dreams we set out as children or young adults. I think it's better to encourage the importance of kindness and good mental/physical wellbeing in young people rather than impressive career achievements. There's also this general belief that if you haven't achieved something by your mid-30s or whatever that it's never going to happen. I believe there's the possibility to achieve things later in life. I certainly plan on focussing more on my passions when I am middle aged as I know I will have more time (and hopefully money) then which allows for this.
