I was shocked when the author of the post said he had had twins and founded his business in the same month. I just had twins a few months ago and founded my business ten years ago. I couldn't imagine doing both at the same time.
I have massive newfound respect for parents, and especially for working single mothers. I have no idea how they do what they do. I am fortunate enough to have a nanny, work from home, and it's still very challenging.
