Cognitive training works when it's tailored to the person. And also — when it's not fighting against factors that quietly drain the brain from the inside.

So this questionnaire serves two purposes:

1. Tailor exercises to you — taking into account your work rhythm, stress level, productive hours, and goals.

2. Identify the "silent thieves" of your 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 precisely I can help. Takes about 10–15 minutes. Only name and age are required; everything else is optional.
