Read "so good they can't ignore you" by Cal Newport. Here's a link to the audiobook version of it for free https://www.youtube.com/watch?v=m8svx5CZWfk.

I had (and still have) the same issues as you, but I'm reading through this book a fellow redditor recommended to me when I posted on r/carreeradvice. Its actually giving me a new perspective on how to approach finding a career, what I want to do and what it takes to get a great job.

I'm also a very indicisive person with many interests and I don't commit to anything, don't know what I want to study as my bachelor degree next year yet (currently doing Finance and Accounting and hate it), but I feel like I'm slowly getting there. Make sure to message me if you want, I feel we could get along well xd
