If you are in pre-school ... GREAT! Your mind is still open.
You simply enjoy playing with the triangles, discovering shapes.
If you went to school, or universities, don’t worry.
Simply forget (for the while) everything that you were taught.
After learning-from-playing, experiencing-by-doing, everything you knew will get a new place in your understanding: integrated, coherent.
It is like a rebirth; it happened to Kelvin Abraham, it can, will, happen to you.
Simply play with the triangles.
Follow the patterns.
Let the understanding fall in place.
Trust what you are doing, and seeing.
This, you may need to do from right now till the end of the course.
You may enjoy keeping an Open Mind till the end of your days of life...
