1. Ali wants to move from point $A$ to point $B$. He cannot walk inside the black areas but he is free to move in any direction inside the white areas (not only the grid lines but the whole plane). Help Ali to find the shortest path between $A$ and $B$. Only draw the path and write its length.

I think we judge talent wrong. What do we see as talent? I think I have made the same mistake myself. We judge talent by the trophies on their showcases, the flamboyance the supremacy. We don't see things like determination, courage, discipline, temperament.

And Pythagorean Theorem, we get that the length is $\sqrt{3^2+3^2}+\sqrt{3^2+4^2}+1+\sqrt{2^2+2^2}+1=7+5 \sqrt{2}$
