What an interesting article. It's a toss-up between the hearth and the mind. But, the first question that has rised after reading it was: Why don't you want to learn both languages?

It is obviously more difficult, but French might make you feel relaxed and you might take the pleasure of learning it while you are learning ( or rather pushing yourself to learn?) Spanish. I am in the same situation. English is a must while French is my pleasure. If I chose French only I would feel guilty. If I chose English only, I would feel unhappy. So, I take the advantage of both! 

Thank you Diana for your kind comment!  And thanks to all of you who read this article.

All the best,

I'd follow my heart to study hard .

That's a great question! I'd follow my heart as I always do in my life.

Whatever you choose, the one thing you'll need is motivation. I think if you really like the language you're learning, you'll be more motivated.
