Yes, you actually CAN go home!
We're so often advised to write what we know -- and for good reason! When we write about things, surroundings, foods, experiences that are familiar to us, our words and descriptions are imbued with nuance and layered with meaning and whimsy far beyond mere mental gymnastics. What may seem hackneyed and obvious to the one writing may very well be a refreshing revelation to another.
So don't discount or even downplay what you know. Polish it and let it shine so that it may infuse your writing with authenticity and richness while delighting your readers.
