Have access to an EIDL loan, what should I do with it?

I finally got [pre?]approved for the EIDL program - I originally applied nearly 2 months ago, more interested in the "free" grant portion of it, which was immediately exhausted and I haven't seen a peep about it since.

Anyway, I am approved for $18k at 3.5% for 30 years ($88/month payment) with first payment due after the first 12 months (it looks like the first year nothing is due.)

I'm curious what ideas people would have for how I could use this? I am just a freelancer with a day job, so I don't need a loan to survive, but if there was something worthwhile that I should be looking into, I am all ears. Using it to bootstrap a new business, or purchase an existing business/idea, etc?
