Dear Reader,

It has been an exciting year. And Christmas is here again.
I would like to thank you again personally for supporting my book project with your order. In the meantime, a large part of the first edition of CLASSROOM THINKTANK has arrived in 18 countries.


Now, of course, I'm very curious to hear what you think about the content. If you have already found the time to start reading,

I would be very happy if you could answer some questions about CLASSROOM THINKTANK.

Thanks in advance - Happy New 2022!

Leonard Summer
