Stimuli

1. Endangered Species
When I think of endangered species, I think of the apocalypse. If an apocalypse happens, the whole human race might be wiped out or the human population will decrease, causing humans to be an endangered species

2. Circles and squares 
For circles and squares, I think of wormholes in space. Mainly because the structure of a wormhole has both circles and squares in it.


3. Success at last!
For success at last, I think of an individual overcoming whatever fear or obstacles that he/she has within her/him-self, such as phobias.
