Midheaven in the 9th house means you’ll likely be know more for your ability to teach, your wisdom, and your philosophical ideas rather than just your career (whether or not those go together for you). You might be known internationally or even for your tendency to travel. Ultimately, this midheaven placement is more of a “thought leader” energy than an “industry leader” energy (industry leader being more aligned with the tenth house). You are in search of truth and adventure.
