I'd like to give you an example: I recently wrote an article outlining several ways to get out of a writing slump. As I was writing that article, I came up with about 7 or so ideas for getting your brain out of a creative rut with your articles, including some article template ideas and some writing productivity techniques. I submitted the article, and then thought__ "Each of those ideas for getting out of a writing slump needs to be elaborated on and explained further. I can do a new article for each idea." And so I did__so far I've bounced 4 or 5 articles off of that first article, and I have even more ideas that I've gotten from that first article that I haven't written about yet.
Of course, the reason why you would like your memories to be mounted to a scrapbook instead of a photo album, is because you would like it to be special as much as possible. When you create a scrapbook of your own, you do not have limitations in adding as much creativity as you want, unlike photo albums, you are entailed to use only the spaces that are allotted for pictures. And since photo albums are ready made, it's difficult to make a personal touch for your own preference.
