Glad that see these questions coming from such young minds!
I would say someone can have most flexible and rewarding career by picking up entrepreneurship. However it requires lots of work to build a foundation to become successful entrepreneur. Keeping this as a north star goal and acquiring required skill for that, something you can consider.
There are other options like freelancing or independent consulting which gives lots of flexibility. However I would have same recommendation to focus on acquiring skills when someone starts career and get ready for the north star goal.
