What an awesome question! Seems simple enough but really it's not. I love these types of questions, thought provoking and inspiring at the same time.
Mmy wish would be to finally finish writing my novel. I've started numerous since preteen years. Hell, even earlier than that lol
Here I am, 32 years old and I've left a trail of hundreds upon hundreds of short stories and unfinished "novels" along with occasional poems.
I don't know why I never finish. I get pretty far at times. My last one I spent two years living through, I grew close to the characters to the point where I agonized over the hell I would put them through. I'm a little out there I guess. Ending is difficult for me, I never manage to get past the initial climb.
But I want to leave behind at least one finished novel, which would of course be my most accomplished piece. I don't care about being published etc, I just want to one day finish that great story that's been burning deep inside my very core since day one. Just waiting to be told. But denied its right to live due to my personal struggles.
I love the idea of something like Emily Dickinson. Leaving behind all of this amazing work that never managed to make it past my own hands. Yet after my death my spilled thoughts impacting others.
Eh, enough babbling.
I love your question. I thank you for allowing me the opportunity to be selfish and carry on about my greatest desire.
One day...
