Educational practice works better when the material fits the person and the context around them.
So this questionnaire serves two purposes:
1. Tailor materials to you — taking into account your work rhythm, stress level, productive hours, and goals.
2. Notice context factors that affect energy and clarity — lack of sleep, sugar spikes, dehydration, overload, insufficient recovery. These are often the real reasons behind fatigue, distraction, and low mood — not a "weak brain."
The more honest and detailed your answers, the more useful the material plan can be. Takes about 10–15 minutes. Only name and age are required; everything else is optional.
