BEST Or MOST EFFECTIVE WAY to learn FINNISH!

Hello... I was just wondering, what is the most effective way to learn Finnish if you do not live any where near Finland? 

What has worked for you? And how?

What do you recommend? 

I would like to gain fluency in this language, how can I achieve that? What courses should I buy?
