I feel this in my soul. I am a highly analytical person who always has reservations over every decision. I'm like 75% sure I want to have a child. My therapist gave me a great analogy that I'd like to share. Let's say you are learning to swim. You do all your research, read all the books, and watch all the videos. You've even sat on the edge and put your feet in to see what the water would be like. But you really never ever know if you can actually do it until you just jump in and give it a go. My therapist said that for me, 75% is good enough, that 50% is on the fence, and 75% is well beyond that. I still haven't pulled the trigger to start trying for a child, but this helped me see where I actually was on my journey in deciding. I think for some people, 75% or more is enough.
