Questions are brutally powerful. So powerful in fact that they are the very source of science itself. The very fact that you're able to read this from where you are right now is due to questions. I wonder how many people have actually studied the history of questions and the impact certain questions have had. In your own life questions guide focus, they guide decisions, feelings, moods, emotions, and concepts.
What would happen if you consciously chose which questions you asked yourself throughout the day? For example, during lunch time instead of the trite & overused "What's for lunch?" we asked "What can I eat right now to build a beautiful physique and enhance my energy level?" Do you see the power here?
The small distinctions questions can make in your life can be a gigantic lever of power. Here are some more questions, instead of "How could he...or...why would she?" we could use "How can I....or...what would it take to...?" The key difference here is the first form of question makes us focus on the problem and the power of it. The second set forces you to focus on the desired outcome. Amazing how simple, yet how effective.
Another trick to making question work for you is to refer the question back to you. This gives you honest responsibility, and thus the power to change things in your hands. For example, "why didn't he buy from me?" would be changed to "what could I do to make the sale?" Even better, in regards to a sale, is flat out asking "what would it take for you to buy?" at the point of sales, instead of second guessing and wasting time after the fact.
Novel forms of psychology stem from these lines of questions. The old school Freudian camp were the proverbial "why" junkies. This psychoanalysis was great at wasting time and making a persons problems overwhelming. Forms of psychology that started asking the "how's" and the "what's" questions actually produced radically fast results. Gestalt, Cognitive-psych, and NLP, were the primordial forms of these evolved, results/goal-oriented based psychology therapies.
To change anything immediately change the question. You'll have the honor of joining a group including Einstein, Newton, Galileo, Socrates, and Leonardo Da Vinci.
