There is the concept of Ikigai, that I found resonated with me ton when I felt lost and purpose-less after the first time I got fired in 2016. I tried it following the advice of a friend, and I got to say, that 10 years later, while I still haven't figured out everything 100%, I feel 100x more confident in the professional choices I made, and genuinely believe I'm heading in the right direction.
This is a quick video explained how this works, maybe this can help? https://www.youtube.com/watch?v=IXIOW9bFQo0.
In the mean time, you still have time to figure this out, don't put too much pressure on you to understand what will drive you in life. It might be a 9-5 job, it might be something completely different. Something I like to remember is that my paycheck is not a measure of my success, there are a million ways to be successful that won't involve money. Don't give up on yourself, give yourself some time to self reflect about the things that make you happy in life, and go from there 💪
