Me, I'm thinking of Ursula Vernon -- a fine artist, writer and gardener I quite admire -- and what she wrote about mulch . While it's a piece about art and the creative process, it doesn't really end there. It makes points like -- well, all of that stuff that didn't pan out as planned; that never really went anywhere; that perhaps was frustrating and pointless and painful at the time -- all of that is compost that can still turn into good soil.
You can mulch pretty much everything. And with many diverse and unexpected things decomposing in your garden, it's rather more likely to yield interesting results than if you stick to mulching the same old things, safe and nourishing as they may be proven to be. I mean, the stuff growing from where you spilled that vat of toxic sludge may be mutated, unsightly and possibly plotting the downfall of all humanity, but just look at the colours, man.
Some of the things you've tried and abandoned may help you out unexpectedly, way down the road.
Don't be afraid to abandon things that aren't working out, and don't obsess over the things you didn't finish. When you stick with things, do it out of love, not out of fear.
The paths of life are unlikely to be straight and evenly paved, which is a lucky thing, because how bloody dull would that be. There will probably be lots of roots and rotting carcasses to trip upon. Still, even the things that appeared at the time to be wasted effort will keep informing the person you're continuously turning into. Who hopefully is someone worthwhile, and whom you certainly have the power to make into someone even better.
So regardless of what you've currently got rotting away in your compost heap, I hope your coming year will draw good nourishment from your mulch, and that the things that sprout from it will be stronger, weirder, wilder, more beautiful than before. Just stay away from the ones with the tentacles, and you'll be good.
Y'all have a wonderful evening, and let's try not to blow up the Earth this year either; it's still where I keep most of my stuff.

A note about commissions: While I do commercial projects whenever work comes my way, I am also open to private commissions for props, accessories, jewelry, and any other stuff that's within the range of my competence. Which includes quite a diverse range of materials and techniques, so pricing is rather on a case-to-case basis. Write me a line if there's anything you're interested in -- after all, asking is free.
