A New Way Home
If you're driving home and the road you need to turn onto is closed, you don't pull over and quit--you find a new way home. You change your plan.
If you're trying to work through something with your dog, but just can't seem to get things going in the right direction, don't throw up your hands and quit. Find a new way home. Change your plan. Take a moment to step back and rethink how to achieve the goal you want. Troubleshoot. Try something different.
Don't give up or get discouraged because the road is blocked. Appreciate the new knowledge you will gain by discovering a new way home. Breakthrough what you think must happen, and find out what needs to happen. There's a reason there is only ONE road to nowhere :)
