I am always going back and forth. Those days when a kid is screaming during nap time or when you have to constantly repeat yourself. I think when you look at the big picture it can become clear to you whether it's a fit or not. I have sometimes said to myself, "OK you're going back to work (outside the home)then" or I look at job boards online and those times I did that I didn't feel relief in saying this or a desire to take one of the jobs. Instead I felt panicked and that made me realize that this is a fit for me right now.
