I'm interested in both Arabic an French but don't know which to pick. French bc I like everything about culture but Arabic bc of my potential use in future career in helping developing Africa and Arab world and politics in general. Help me please?

Do both!! If you can't, it's probably better to do a more future-career based language, in your case Arabic, because it will get you further. But once you have learned it, you can learn French as a  hobby considering you don't NEED it for a possible future career. :)
