Don’t be too believing;
Don’t believe all that you hear;
Don’t think you’re still a child;
Don’t misbehave;
Don’t sell yourself short;
Don’t give up so easily;
Don’t be so lazy;
Don’t feel bad;
Don’t be frightened;
Don’t be surprised;
Don’t deceive anyone;
Don’t be unkind to another;
Don’t think you’re too young;
Don’t think you’re too old;
Don’t look for excuses;
Don’t travel in the night.
Don’t speed when you drive.
