writing learning thinking
You think you KNOW when you learn, are more sure when you can write, even more when you can teach, but certain when you can program.

concept include seek
Symmetry is a complexity-reducing concept (co-routines include subroutines); seek it everywhere.
nests ballpoint-pens parentheses

variables
