Think of an animal that doesn't exist . Give it a name and be specific about it’s diet , environment and any other detail that seems important in its existence. If you are feeling artsy paint it too.
What is the difference between an animal and a human ? Animals can think and love like we do but it is the capacity to imagine that makes us special. We believe in what the eye can't see and have created a whole world of magic (like phone calls ) thanks to our capacity to imagine. Money for instance is just paper until we imagine it has a value. So exercise your imagination as much as you can and you will find yourself finding more creative solutions to your problems.
