One of the things that always ticks at the back of my mind is that we only ever get one shot at this. Many days, it often feels like we can try try again – but much of life is once and done. The kids aren’t babies anymore, and I expect I will never be a father to a baby again. I expect I will never start a company again. Go caving again. Do a triathlon again. Maybe – there’s always a chance. But it’s strange. I will never be who I was again. I can only become who I will be.
