So, I was listening to music, when I started thinking about architecture, and how some features in old buildings are there for religious or occult reasons, and my chain of thought made me start making a list of symbols, with meanings of my own devising. (Drawing inspiration from other sources, of course.)
Either way, I figured I might as well post this here, in case anyone might suggest a use for the symbols.
I only really designed four, which are as follows:
Circle - Infinity, repetition, and (this one is mine) inevitable circumstances.
Circle, with line from top right to bottom left - Shortcuts, cheating, futility (because there is still no end)
Horseshoe, upright (U) - A long path, effort, fruition with time.
Horseshoe, upright with line connecting the two ends - Speed, efficiency, possibly recklessness.

Anyway, that's all I got before my pencil broke. Please post thoughts!
