Did you know that the part you hold in your hand when filling up with fuel at the end of the hose and inserting it into the opening of the tank is called a nozzle? I was not aware of it. It happened to me when I was driving and had to refuel that I didn't always know how the part worked. In the dumbest case, I'm at the petrol station, it has fuel, I have enough money, the tank is empty and ready for pick-up - but I'm incapable of operating the infrastructure correctly. And then if it's a marginal time and there's not another person around, all that set-up is of no use to me. Experience and knowledge are part of learning processes. We sometimes forget that and sometimes claim to have a qualified opinion on everything - which, of course, is correct from our point of view. Perhaps today is a day for conscious moments of humility.
I wish you an extraordinary day!
