Wise father, it seems that until we are grown is when we start realizing just how much life experience and know how they have. Our kids are like we were, unbelieving and scoffers. My dad's best advice and I still believe it is when he told me that the lazy work double. In other words sometimes we take short cuts thinking that we'll save effort or time but in the end it was better to do it right the first time even if it takes longer. In Spanish it's "el huevon trajabja doble".
