Dear Chad, I have watched all of the lessons. I have not in the past done a lot of puzzles. Some of the techniques you have presented, e.g., one through nines, thinking outside of the box, I have done by accident, I suppose. I just was not doing them with any structure. You have helped me great deal there. The techniques of the double doubles and the triple doubles were new to me and they are invaluable. I cannot thank you enough. The easy level 1 puzzles have become very easy to do and I have successfully completed a few level 4 puzzles that in the past would have taken much longer to do. I probably would have just given up on them. Thanks a lot,
