I actually love when someone tells me it's impossible or unsolvable. Maybe that's my Aquarian rebellion surfacing--I've never liked being told what I could or could not do, but I can't help it. I love to solve a problem. I love to sit and let the wheels turn and look at the problem from every angle, testing this seam, prodding that one.
Because here's the thing--I'm convinced everything is solvable. And if I have some puzzles I've not yet solved? Well, their time is coming. Time--that's another side of the problem conundrum--some things can't be solved in the timeframe we have in mind. Some problems require props and resources for their solutions--items to be acquired or learned one at a time until the collection is assembled and we have what we need to get the job done.
But it's progress--and progress is a massive cog in the problem-solving machine. Luckily, the delight of the glimmer of a solution is enough to keep us on fire, no matter how long the solution spins itself out.
