Rembrandt did more self portraits than any artist I know of. He didn't use a computer or photographs, just a mirror. . He was all about practice and experimentation. I wonder if this was before or after washing his hair?
Another favorite artist and superb draftsman, Albrecht Durer. I wonder if he was thinking, " Nothing to draw today, might as well try another self portrait...". He did this at about age 23.
I often think of the conditions they painted under. No camera, no Blick Art supply store down the road, no computer, no Borders Book stores to sit in for hours to look at all the art magazines. They just had pen and paper and a mirror.

Self Portrait - Day 22
pen and really old India Ink on paper
I haven't used a quill pen and india ink for 30 years.... Wait a minute! I think I was using this same bottle of ink back in art school.
