need to do

I know I want to be a professor after I get my PhD, because I love teaching. However, I also know that I need my research/work to involve some kind of application where I get to work directly with people, or else I won't feel like I'm doing anything. So, sometime soon, I think I need to figure out exactly how I want to apply myself and exactly how I can start getting some experience in that area. Based on this, I can try to determine whether it's worth it to continue taking Arabic, or whether my time would be better spent on other pursuits.
