Every time I look through photobooks I already have printed, I have two thoughts.
1) I should never ever ever get an album printed again, because my style changes so drastically and I improve so much year-to-year that the older books look so outdated (and even some of my newer ones are getting that way because I grow and learn so much). It's a cringefest every time.
2) I need to print MORE photobooks. Just as I grow, and my son grows, and our life changes and improves and things go through stages, so does my style and my scrapping. I'd rather have outdated, but tangible, hold-in-my-hand albums, than a bunch of albums on a hard drive that no one ever sees because I worry they aren't good enough.
Do I want to go back and re-do them? Heck yes. Are some of them embarrassing? Oh, totally. I have an album from before I discovered drop shadowing, and I kind of want to cry over it. But they tell a story, and I had to eventually get past hiding them from the world and instead display them proudly on side tables.
I think it's a problem a lot of us experience. I look at my pages and think "I wish I would have embellished here... or added x title here... or done this... or dated that..." but I learn from it and just try to make sure I work harder on the newer albums.
It's a process.
