"When you have exhausted all possibilities, remember this, you haven't."

-Thomas Edison.

You think that you’ve thought of everything. There’s always another way. You just have to find it. It might take a bit of imagining for it to become a reality. It’s a good incentive to help you not give up, though you might have to give it some extreme thought. Perhaps you could create some technology to help you. Or maybe you could look to nature for inspiration. Perhaps another species already has the solution, and you need to adapt to it as much as possible. It’s important to not give up, but you also have to recognise when to move on. Perhaps there’s a way of skirting around it so that you can work on something else and come back to it later. There’s other people here too. It’s going to be a way that you haven’t thought of, and you may need to ask others for their insight, or at least follow in their footsteps for a while. Perhaps you can inspire them to get the task done.
