Lighthouse:

A tower with a light on top, located at an important or dangerous place. Two main purposes are to serve as a navigational aid and to warn of dangerous areas nearby. 

Do you find yourself wishing you could've seen an obstacle before you stumbled over it (figuratively speaking)? I have realized that surrounding oneself in a community of like minded people [creative, faith based, etc...] serves as a lighthouse for the journey you are on. They out of love and care for you will point out when you seem to be straying off a path or if you are heading into a rough patch. While also shedding light and helping you sort out the difficult things you may be facing. 

I hope you've been able to surround yourself in a community as such or are able to.
