Today, I was cleaning up the space in Google photos, and found many videos and pics of my son when he was young. It reminded me of how energetic he was. He did a lot of sports and activities. I am afraid that we have made him uninterested in pursuing excellence of anything. How to motivate him? How to keep it sustained. Is it OK to do non-science? Sure. Anything at all. Business? OK. Let's think about this and put the plan in motion. I know it is never too late. It only gets a bit harder as time passes.
