It means you need to stop day dreaming and do something creative. Or, you need to make a paper airplane.
paper airplanes, definatley!
The earliest reference to paper airplanes I know is that Jack Northrop used paper airplanes in the 1930's to help in his ideas for flying wing airplanes.I believe that I can extend your history of paper airplanes back to at least 1908-1909.
Paper airplanes can be nominally divided into groups such as "darts" and "gliders", though the two groups are verygeneralized and contain many subgroups.

Lift, weight, drag, skill and luck (to give it the right amout of kinetic energy).

Generally, it is optimal to make a paper airplane symmetrical. I am not sure I understand what you mean by type of symmetry. However, some paper airplanes can be designed to be asymmetric and remain straight flying.
Paper airplanes act differently when wind acurress. And it may be hard to fly. UNLESS it is flying in the way of the wind,which allows it to "flow on air."If you put a paper airplane in a mild, suttle wind way, it will go smoothly. But with rough, ragged windswill lead to a fatal crash of a piece of paper.
Lift makes paper airplanes fly, just as it does real planes.magic
