When finally I met my dad in my adult life, he couldn't show me any photos because his house had burned down.
[As an aside: Some years later he was gone, and I traced my 4 semi-siblings. They had almost no images of him and I was able to show them what he was like as a young man.]
Not a bit of it. You're an amateur.
I put the book I might finish one day onto 4 sticks, Seagate Black Armour LAN thingy. One DVD in each American son's house. I carry a SD from my camera cos it's thin, and store files on there. It takes up very little room under my driver's license. Oh, yes. It's on all the lap-tops.
I suppose there's a very high chance I'll lose one of them and someone will nick my work.
