Contemplating a Fixed Income

I am on vacation this week (but staying home and relaxing) so my paycheck will be just for straight hours. Usually my paychecks are bolstered by shift differential and taking call and such so there is some flexibility in how much I make. I was thinking about what life would be like if my income was fixed, as it will be when I retire. It was a scary thought. The result of this contemplation is that I feel more committed to making sure I have a really good retirement savings.
