Photograph yourself
If, for some reason, you'd like to take a quick snapshot of yourself without asking others for help, the easiest way to do so is with a digicam with a screen.
Imagine a mirror, if necessary a pane, or other reflecting surface, keep the camera at the necessary distance from itself, check in the mirror, what the camera screen displays and correct in this way, if necessary, unfavorable attitude, stupid grin, hair / Clothes breakdown and press the trigger.
You will be surprised, the picture will be something to be proud of, in contrast to "blind" shot shots, which are rather a matter of luck, unless you are practiced in posing.
Of course, an arm's length is only enough for a slightly larger portrait shot, but if it serves the purpose, why not ...?
