Thank you so much, Silvia.
Yes, a deep WHY will give you the power to continue when everyone else would have given up due to their weaker WHYs. No one can ever know when their next breakthrough will happen. I read a story about a gold mine back in the old prospecting days.
One prospector dug and dug without finding anything. He was so sure that the gold would be found as he saw the signs, but he go so frustrated with it that he left and sold the mine for a pittance. The new owner only dug 10 more feet before he struck a motherlode and became extremely rich!
