With French, my biggest advice is LEARN YOUR VERB ENDINGS. French is actually quite easy to speak passably in my opinion because word order doesn't have many challenges, and you can fluff nouns by pointing, frenching the english or describing the thing, but without verbs you're getting nowhere. I had a bit of a shock when I spent two weeks in France recently and my French had just died on its ass.

I was going to take Russian and German at uni but took a year out to, among other things, see what dodgy Russia was going to get up to. Thank god I did, because taking languages in UK universities means spending a year abroad in that country, and Russia is not the place to be right now - I transferred to German and Dutch instead.

I unrecommend the Sims 4 character creator having now actually tried it.
