Growing up our family sayings were:
“When the going gets tough the tough get going” and “what doesn’t kill you makes you stronger”
In my home currently our sayings are:
“It’s better to be kind than right” and “…because we are a family” You can help your brother, because we are a family. We can overcome this struggle, because we are a family. We can accomplish this goal together because we are a family. You get the idea. I use it a lot with my kids.
