What have I done?

Sometimes I feel old and I look back on my life so far and wonder "what have I done with my life?". I start to feel like a pretty big waste, thinking about all the potential things I could have done or should have done and really feel pretty worthless. Then I'll get a call from my daughter and I'll listen to her chat about her day, and I can hear my grandbabies in the background, or I'll get an e-mail from my son telling me about his promotion to FC2 and I am filled with a overwhelming sense of pride and joy. Now granted I can't take all the credit for how they turned out, but I like to think that I may have had a small part in making them who they are today. Okay maybe they learned what not to do by watching their mom, but still they learned and look at them now. They have given me more than I could ever ask for, and I thank God that he gave them to me.
