But don't get overwhelmed thinking you have to print EVERY photo you take. Our parents and their parents weren't taking selfies multiple times a day or taking photos of every meal they ate. They were much more selective in what they chose to photograph because film (and film developing) cost MONEY. Take a minute to think about how many photos you have from your childhood. I'd safely say NONE of us have THOUSANDS to peruse. Most of us probably have a couple hundred documenting our ENTIRE childhood years. But that amount is enough to bring back special memories and remind us of our younger selves. So pick your favorite 20-30 photos every month (maybe more if there's a special event) and print them out. I highly recommend using a high-quality printer, such as mpix, who uses archival-quality photo paper. I also recommend storing them in archival-quality albums and/or boxes for long-term preservation in a temperature-controlled room of your house. Chances are quite slim that our homes will be destroyed, so these photos most likely will outlive us by decades or longer. I recently held a client's family photo that was over 100 years old and it was in GREAT shape, all things considered.
If we truly DO have a digital dark age in the future, those couple hundred photos per year will more than tell our stories to future generations.
