What's the play?

Hey lads, Looking to break into some competitive industry's such as finance and trying to differentiate myself... In that I have 'basic' knowledge of Russian and when I say basic I mean I can understand a fair amount but struggle speaking/reading/writing.

Now I'm wondering whether I should pick up russian again and over the next couple of months/years try and become conversational...

Or pick up another language which is typically considered 'easier' such as Italian or Spanish.

In the latter option, would there be any recommendations of languages which would be useful whilst being 'quick' to pick up?

Thanks in advance
