What did you sacrifice to be a SAHM?

If I were to become a SAHM, I would definitely have to keep my spending in check. We would need to give up cable TV, gardener, housekeeper, meal planning would become a must, no new clothes, I would need to learn to cut DH's hair, no costly outings, no trips, we would hardly have enough leftover to save anything. I think I could live without all of this. but losing the financial security that 2 jobs provides is scary. Especially if I were to keep working, we could potentially pay off our house in 5 years. That seems huge to me.
