I would say that it may be unwise of you to be so direct about it with certain employers who are looking for long term ATSA staff.
Simply state (better than I'm about to) that you're ambitious, driven, highly motivated and seek to better yourself at every available opportunity. The worse thing you could do on any application and during any interview is to lie and say that you're not interested at all however.
Just don't be so direct and demeaning about it
Oh and Squadgy, check your PMs....
