I'd like a basic aspiration to reach the top of a career.

Very few careers have an aspiration to go with it, while it would be a lot of work to add aspirations for every single one, I think a generic one could be a solution that works for any career. 

The final goal would simply be to reach the top of a career that is not an active one. 

Choosing the direction in the career could be a goal too, but either choice would be fine. Just reaching that point would be a goal. 

Getting a job would be a starting goal. 

There could be other side goals like become good friends with a co-worker, get a positive outcome from opportunities a certain number of times, get a certain amount of money from bonuses, etc.
