I remember creating a math library in Apple BASIC, and a stamps collector application for my father, with its own database system way before I learned what a database was. Learned Pascal, and tried learning assembly but that was too advanced for me. I was in highschool, so many memories in the Apple //c!
Some more interesting things that I remember:
The packaging of the computer smell to apples and lasted many years.
Lots of experimentation with graphics and colors (with a green monochrome monitor), sound, poke/peek, disk and file formats, etc.
Trying to create a 3D vector game about a robot exploring a haunted house, got to complete a stairway climbing scene.

Playing some of my favourite games of all time: Wolfenstein (predecessor of the 3D versions), and Bard's Tale.
Testing a self-replicating virus in Pascal from some Polish magazine.
Trying to wire a circuit to the joystick port, causing sparks and damaging the port :d
