Dann / Then Du kannst es schaffen / You Can Do It Sie / You
If you think you can do it, you can.
If you can do it then why do it?
It ain't bragging if you can do it.
If you dream and you believe, you can do it.
If you can dream it, you can do it.
If you do not believe you can do it then you have no chance at all.
You can do what you have to do, and sometimes you can do it even better than you think you can.
I don't think anything is unrealistic if you believe you can do it.
