How do you know you have done a good job?

Raising children~How do you know you have done, or are doing a good job? I guess from day to day you can not see the evidence of a "job well done". But, I am sitting here in the hospital room with my husband, father-in-law, and mother-in-law. I just realized that when all is said and done, the evidence of a "job well done" is perfectly clear. This pictures shows a loving son and a dedicated husband. This is a very sweet picture to me. These two men have shown more strength than I have ever witnessed in my life.
