I find that many people my age are quite lost.  They don't know what to do with their lives, they don't know what their dream job is, they don't know what their purpose in the world is, and they don't know the meaning of life.  And that all concerns them.

So they meander from one temporary thing to another that doesn't require too much responsibility, nor too much commitment.

You're going to be alive for decades longer, and the age expectancy keeps increasing.  Or you're not.

Don't worry about what you will achieve in your life and what legacy you will leave behind.  Instead, figure out where you will be in 3 months.

At the same job?  Still studying?

Studying a language overseas?

Working on freelance gigs?

Your next project?

Wrapping up this project?

Organising a conference?

Life may be decades longer.  Life may be a century longer.  Or life may be a week longer.  You never know when you will live and when you won't.  So stop trying to figure out what your ultimate dream will be, choose a project, and start pursuing that for the next three months.  Your project doesn't have to be your ultimate legacy or represent your ultimate meaning in life.  That's too much pressure.  Just choose a project that's "cool enough" for you, your skills and where you are in life.  Putting too much emphasis and pressure on it makes it too scary for you to start.  "Cool enough" could be something you learn a new skill out of, (such as management, leadership, coding, building, speaking), it could be a course, it could be travelling, or it could just be a project that sounds exciting.  By pursuing "cool enough" projects three months at a time, you will find meaning in your life, you will create a legacy, and you will find purpose.  Not in a big moment of epiphany, but in many glorious unravelling of moments.
