be made of sterner stuff
To be very strong, determined, or of uncompromising character, especially in comparison to others. Having to take care of both of us growing up, my brother George was made of sterner stuff as a kid than anyone else I knew. I can't believe you let us down at the last minute. I thought you were made of sterner stuff than that!
