What a great Christmas gift! Thank you so much for this video! It is so interesting! I'm going to watch it twice. 1 time in order to just enjoy it and another time to calculate alongside you, what my personal estimate is. I really love this video and I wish you'll create more videos along these lines! I discovered you this year, so I'm quite new around here, but I still wanted to thank you for the many hours you have already contributed to my life. Your work is great and since we have a similar way about our personalities with our need of organization and self-discipline, I thought I'd let you know that I benefitted from learning about you in a more personal way from your more personal video about your daily routine. Thanks for everything, I wish you success, aliens, and a happy holiday [:
