Conversations on the Traction Heroes podcast are proving highly relevant. To wit, episode 7 delves into how the questions we ask ourselves influence our ability to act skillfully. This came up in the context of dealing with uncertainty. Specifically, Harry brought to the conversation the following fragment from Rich Diviney’s book Masters of Uncertainty: To remain grounded in the sphere of what you know and control, cultivate a habit of asking yourself better questions. The brain operates with a question-answer mechanism: it continuously assesses the surroundings with questions and then conjures answers. This typically happens subliminally and instantly, faster than you can notice. You can, however, participate consciously in this process and influence your thoughts and feelings by introducing your own questions. When you introduce a question into conscious thought, the mind is compelled to come up with answers. The problem is that it’s all too common to default to reactive, negative, and sometimes emotion-laden questions such as “Why am I so bad at this?” or “Why can’t I succeed?” Your brain will immediately begin to give you answers to these—yet the answers will not lead to enlightenment. Rather, they will spiral you into further negativity and anxiety. Masters of Uncertainty steer their thoughts with better, more effective questions — questions that center on what they can ascertain and influence. Well aware that knowledge morphs into power, they prime their minds with inquiries like “What do I know? What can I control?” The brain can’t help but answer these questions in ways that put you at the helm. These are the inquiries that empower and hone your focus on traversing uncertainty, not succumbing to it. I hadn’t heard of Masters of Uncertainty before, but I’m reading it and hope to do a book notes post soon. Working with uncertainty is especially relevant now, given the changes rocking global markets. At least part of the secret to navigating turbulence is learning to keep your cool. It’s not a new idea (the Stoics and Buddhists said this centuries ago) but it’s worth revisiting — and internalizing. Traction Heroes ep. 7: Better Questions

A conventional model rocket engine is simple combustible solid fuel (black powder or more advanced composites) molded into a cylinder that uses expanding gas to produce thrust. Though it is minimal, there is some danger there. An alternative is compressed gas, which will also expand to produce thrust — just without the explosive chemical reaction.
