Hope can be a powerful force. Maybe there's no actual magic in it, but when you know what you hope for most and hold it like a light within you, you can make things happen, almost like magic.
If you're trying to achieve, there will be roadblocks. I've had them; everybody has had them. But obstacles don't have to stop you. If you run into a wall, don't turn around and give up. Figure out how to climb it, go through it, or work around it.
