The whole project started around ten years ago which is when I started learning with David. I had been out of Gemara learning in depth for some period of time so when I sat down with him and started learning again it surprised me greatly the depth of his questions and answers. It reminded me of my first yeshiva Shar Yashuv when I was learning Ketuboth and heard amazing depth from Naphtali Yeger.
This gave me an insight into Gemara learning and also has a side benefit that I realize how long and how much effort is needed to approach Physics and Math also.
People get the idea in school that if they do not get something right away that they are not fit for it. I realize now that that is wrong Some subjects simply take a long time and lots of effort.
It took a lot of trials also. You have to get through a lot to be able to see the truth and value of the Torah.
