Actually, people with whom I communicate have a high rate of failure to
understand.

It seems to take you many tries to write what you actually mean.

I must often illustrate concepts in many different ways before others
understand.

The above difficulties in your ability to communicate arise from the fact
that you are an idiot and no one cares what you're trying to say. However,
the point is moot, since you also have nothing to contribute since you don't
fly and never have.
