This great thread seems to mean different things to different people, depending on how the concept of UL fits their life. Dale's Hypermaterialism post, Miguel's 'Ultralight mind' from a previous post, and these recent posts have helped me understand why UL resonates with me. After years of HeavyWeight materialism and being owned by my possessions, I made that leap that Dale talked about earlier and basically re-started my life with about 1 m3 of stuff and a new job overseas. Quit my job, sold my house, finished a divorce, etc. Without realizing it, I have been pursuing Miguel's ultralight-mind; with some success. It might sound strange but I have similar rules for my personal relationships now as I do for my gear; no more dead weight or negative influences allowed.
Just as the UL philosophy teaches that the lightest 'tool' is the knowledge in your head, in my career I have come to rely more on my knowledge than on superficial symbols of success. When I consult a client now, I use the same technique one of us might use converting a traditional backpacker to UL. I strip the clients program down to the smallest number of indivisible essential requirements for success and find the most economical (not just in $) solution, and relentlessly iterate that process until completion. It is quite an opposite approach from most consultants who pad the process with heavy jargon and procedures. And interestingly, most UL techniques I learn here have a parallel theory I can adapt to my work. (I don't mean wearing a shadow-hoodie to my next client meeting, I mean the UL philosophies :) I apologize if I have digressed from the original theme of this thread.
