My answer was quick and easy...
A scrapbooked life is a celebrated life.
My trip to Yellowstone National Park wasn't a week long back in 2016, it's still ongoing in a couple books on my shelves. I loved our trip to Yellowstone. I had fun in the moment. But, then I was able to relive it through all of my family's photos as I was editing them. Then as I created the pages I got to tell the story. I remembered what we did to keep the kids engaged in the beauty outdoors and not on their phones. I remembered that I got to pick where we went on my birthday. I remembered the board game Scott packed that we were able to play at the hotel. I remembered how in the middle of a Yellowstone vacation my family went to see a movie, Storks, and laughed uproariously despite ourselves. I remembered how it took so much work to get the kids to engage in nature, but as soon as we got back to the hotel they were ready to walk around West Yellowstone playing Pokémon Go. They were totally engaged then. Ben was 15 and Emily was 16. From the way they acted on the trip I didn't think they enjoyed it. Later, Ben wrote me a letter for my Mother's Day gift in which he said how much he loved that trip and that he can't wait to go on the next trip I planned. What?!? So, now I look at those books on my shelves and remember Ben's letter too.
I want to live a scrapbook worthy life. I want to see beautiful things. I want to have experiences worth journaling about. This alone will give me a wonderful life full of beauty, laughter, awe, friendship and reflection. That's why I bother.
Bonus... my kids, grandkids, etc. pick up my books and go on my adventures with me. My kids will remember that they had an amazing childhood. It will trigger memories that they had from the same evets in my books and will start to share with friends and family.
