testimonial

...your basic qualities are things you can cultivate through your efforts,your strategies, and help from others. Although people may differ in every which way - in their initial talents and aptitudes, interests, or temperaments- everyone can change and grow though application and experience.

Dr. Carol S.Dweck Mindset

testimonial

Rolf Dobelli The Art of Thinking Clearly

testimonial

...They are not to blame for their problems and their hindrances, but they are still responsible - always responsible - to move on despite their problems and to make the best choices they can, given their circumstances.
