Compared to, say, Russian or Ukrainian French is really not that complicated. It also has way less "exceptions to every single rule" than English. You should choose a language based on your goals, not "how many countries use it" (and even by that metric French would still be really high up). For example, if you ever want to work in Canada knowing French would help you a lot more than knowing Spanish.
>From 2000 to 2009, no province had lower so-called “firm entry” than Quebec. In fact, in the manufacturing, retail, transportation and finance sectors, more companies went away than were created. No other province had that level of “destruction” without the customarily accompanying “creative.”
