What job did Doon want?

I'm curious, can you tell me more about what kind of job Doon was aspiring for? Did he have a specific role or industry in mind, or was he open to exploring different opportunities? What motivated him to pursue this particular path, and what skills or qualifications did he believe were necessary to succeed in his chosen field? It would be fascinating to gain a deeper understanding of Doon's aspirations and the drive behind them.
