I agree with a lot of what's posted here.
For me, there is no such thing as neutral. We live in a world created by God, Earth is his footstool, so in essence, we live beside Him at all times - it's just that were so small and we sometimes fail to see the big picture. That said, even drinking coffee can be godly, for it nourishes us.
Just keep the golden command in mind - do unto others what you would do unto yourself (or to God, for anyone who does to the least will also do unto Him,) and remember the fruits of the Holy Spirit. When in doubt about the morality of a thing, you can more identify them through their fruit. A good tree always bear good fruit, while a bad tree bears bad ones. By their fruit you will know them.
If still it fails to be identified, you can choose it, for it's still, most likely, within the perfect plan of God for your life.
