How do you deal with your disappointment in your child?

I never try to show it but it is there. I am very frustrated with a few decisions but I will live. How I never thought I would be responsible for another human let alone 3. I hope and pray most of what I have instilled in my children will stick and they can make GOOD decisions. Sometimes we have to let them know they messed up in order for them to know they can do better. This was just on my mind whereas I felt I needed to just "put it out there"
