Teacher I studied for teacher German and Economics. I was fascinated by the way to explain things in a very simple and effective way.
Step by Step I found out that you shouldn´t tell people what they must do and how it works, They should experience themselves how it works. This in a very effective way, starting simple and getting a little bit harder with every step that follows.
In practise Meanwhile many people read my manuals to improve their engineering and composing skills. They are very thankfull and I am very proud with the results.I hope you will discover the same they did. So enjoy !
