My biggest challenge is to not second guess myself, and trying to stop worrying all the time.
For example, the other day I asked my 16 year old to pick-up my 8 year old at daycare. I had to work late (hubby out of town). It is only a mile in a half away from my house. I was so worried the whole time, I couldn't work anyway,

and I was second guessing letting them drive together. My mind plays tricks on me when I worry.
Oh everything turned out alright,
