My current fish universe is legit a concoction of ideas going as far back as 2015. I have no fear about recycling stuff or even reinventing (or contextualizing) old ocs until I find something that fits.
Adding onto this:
You can reiterate on ideas YEEEEARS down the line. You can steal ideas from a younger you, you can remake, rehash, reuse, recycle things you did before but didn't do "quite right" too!!!
Reuse a sketch or even a finished piece! Who would even know!!!
