French - 4 years, Italian 1 1/2 years, Japanese - going on a year. My main focus is French and other others are mostly for my own sick enjoyment. I really would love to take a year of Russian before I go to grad school, which means I have to start it in the fall. I'm having a heart-attack trying to figure out of I should switch Japanese for Russian or stab myself and take them all (three at once is fine, but I'm not really sure how I feel about 4). Next semester will be my last of Italian and I'm finished with French grammar courses.
I'm leaning more towards just 3 languages, but the possibility of taking 4 intrigues me and I'm curious as to what other people (who actually care about languages) think about this.
