Do you ever feel like there's no way to explain your life, not because it's a mess but because strange things just happen to you on occasion? That was me in February, when OF COURSE TSA checked my bag the day I was traveling with three random books and some canned okra. (Side note: I felt vaguely like a criminal for transporting okra across state lines.) But here's the great thing about the randomness: you can absolutely use it in your writing.
We all know the old adage that "truth is stranger than fiction." This is why I encourage you to tuck these little incidents away for future reference, when you may need a bit of comic relief in your novel or even simply a bit of characterization. Why NOT write about the girl who packs okra in her suitcase? Maybe there's a good, solid reason for it. Or maybe that's a wacky thing this character does because she's afraid of eating anything that hasn't been canned. Either way, there's a story in there somewhere.
So embrace the randomness next time it happens, and see where it leads you.
