I'm worried about my future...

2023... A new stage, I don't know what this year holds for me. Next month I will enter the university, it will not be the career of my dreams, but it will be a career that may be profitable for me in the future. But in the meantime... what do I do? What do I do until that day comes? How do I earn my bread while I'm studying? It's something that puzzles me...
