Dich selbst / Yourself Sei du selbst / Be Yourself
If you can't plagiarise yourself, who can you plagiarise?
Remember to always be yourself.
There's no one to stop you but yourself.
Do the best you can with yourself and hope for the best.
Accept yourself, love yourself.
Know yourself to improve yourself.
Trust in yourself.
In business for yourself, not by yourself.
You have to believe in yourself.
