Answer:
I am the fountain from which no one can drink. For many I am considered a necessary link. Like gold to all I am sought for, but my continued death brings wealth for all to want more.
I am so simple that I can only point. Yet I guide men all over the world.
I am a precious little thing, dancing and eating all the time. Watch me from a distance, so you can feel my warm and gentle love. But don't come to close or my next meal you could be!
What is that you will break everytime you name it?
I run through hills. I veer around mountains. I leap over rivers. And crawl through the forests. Step out your door to find me.
I have two eyes in the front and a lot of eyes on my tail
