If you are curious, you'll find the puzzles around you. If you are determined, you will solve them.
In my teaching, I enjoyed creating models to clearly communicate my thoughts.
Once I completed the Cube and demonstrated it to my students, I realized it was nearly impossible to put down.
I wanted nothing else than to make the object as perfect as possible.
The problems of puzzles are very near the problems of life.
Our whole life is solving puzzles.
