Certain articles are exclusive and part of a challenge. These challenges have been put together especially for you. They include:

• Digital process; so you can concentrate fully on the content.

• Carefully researched (exclusive) articles on the topic; Inputs from psychological findings and 16 years of personal experience.

• Links to scientific tests; I strive for the best price/performance. Paid tests are therefore not included in the price.

• Exercises for practical transfer and the necessary inputs.

• Knowledge quiz, self-reflection and feedback.
