I like your policy of Tread lightly and l9ve deeply, I believe that should be the main mantra for any success. And the questions pertaining to 'why' and 'what if', reminded of my days working in a school, 10 years before, where a child was very particular to get the answer from the teacher of her why. She never gives up until she gets an appropriate answer. Now she is in a good ppsition. Nice memories. Have a good day.
