I will say from experience, I have learned that it can be difficult if you only surround yourself with those who are unsaved. They possess nothing good that can be added to your walk, usually they can only cause you to stumble, so you need to be careful as you grow in maturity. I'm one to believe that passage has more application than just speaking about marriage or business dealings, though many will disagree.
At this point in my life, I tend not to surround myself with a large circle of friends but I do have many lost family members that I am frequently around. I don't avoid them, I just try to always be aware of my witness though and avoid situations that may cause me to stumble. Many times the lost will try to bring you down, more so than you bringing them up. You'll probably find as you continue to grow in faith, they will tend to seperate from you (darkness can't fellowship with light either). I've been in many circumstances (even church) where you wouldn't even know someone was a believer in a group of people.
If your a born again believer, let that light shine no matter where you find yourself. Sometimes believers tend to hide it when around the unsaved, but that's when it really needs to shine. Time is running short, you'll have eternity with family and friends, it's just a matter of which one's will be there with you.
1 CORINTHIANS 1:18 For the preaching of the cross is to them that perish foolishness; but unto us which are saved it is the power of God.
ROMANS 1:16-17 For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth; to the Jew first, and also to the Greek.
For therein is the righteousness of God revealed from faith to faith: as it is written, The just shall live by faith.
