A guaranteed attempt

What’s something you would attempt if you were guaranteed not to fail.

I think I’d like to do something a little silly with this prompt. A guaranteed unfailable attempt? I could say just about anything.

I could say I want to attempt to bowl a perfect 300 game, or make the world’s most perfect pastry. What if I said I wanted to attempt to discover the most efficient and stable source of near limitless clean energy and make it easy for anyone to produce so that greedy power companies can’t control it?

Maybe I’ll just take that perfect 300 game.
