Ooh spooky close. I was 14. I though I'd invented a whole new kind of array. I dubbed them k_arrays (for kickass arrays of course.)

When I was 15 I took my first real programming course. Soon I was a bit sadder and much wiser. Fortunately, it was just part of the cirriculum. I managed to learn the lesson without ever displaying my shocking ignorance and bringing shame to my family for generations. (not to mention completeling the homework implementing a simple linked list with much speed)

The really sad part is, despite all my enthusiasm, it never once occured to me to link them in both directions to enable bi-directional traversal. Half-assed indeed.

Ah memories - I 'invented' a fully recursive compression algorithm when I was 14. Oddly enough it didn't work nearly so well in code as it did in my head, and the impossibility of successfully extracting an infinite variety of information from a few bytes didn't cross my mind :-)
