i think it might make sense to mention that I had a really wonderful time in shar Yashuv and the Mir in NY. {I had however to leave on sour notes. The Rosh Yeshiva I think had noticed my wild side and so the shidduch with his daughter Penina was called off. In the meantime, my future wife Lea Finn was actively pursuing me and happily I gave in to her request of marriage. I think without her active pursuit of me and her never giving up, is the only reason that I have any children at all.} But at some point, I decided to come to Israel, and even then I could have continued in the kollel system but I was somewhat restless and had discovered Rav Nachman’s advice about talking with God as one talks with a friend and so when I got to Safed I spent most of my day in that sort of activity and neglected learning Torah except when I got home at night and my wonderful wife make dinner with spaghetti or other dishes and after the meal would sit at the table and do about one daf page gemara and one page of the major works of Rav Nahman. But I was not doing what you would call in depth learning iyun. and I really was not able to do iyun either. In spite of my years in three great yeshivot I never caught on to what it means to “learn in depth.” [I think you need talent for that, and IQ also.] It was only when I got to Uman many years later, and David Bronson accepted me a a learning partner that I lowly began to understand what it means to learn in depth. Hi path I might mention was close to shar Yashuv. The hedgehog model- close to the ground. The Mir in NY was closer to the Eagle model of looking at all of shas from a global perspective from there to the subject at hand. I agree that both paths are important. In fact, I have tried to continue in the way David showed me of electron micro-scoping tosphot but at the same time looking at rav shach. The Rav shach approach is continuation of the Brisk approach
