I'm a strong advocate for taking way to many pictures. I have a film camera, a digital camera, my iPhone's cameras, and one of those plastic Poloroid-esque cameras. I'm constantly telling my devices that their storage isn't full because I want to fill my life to the brim with pictures.
I'd like to immediately not dedicate this to my high school photography teacher, she gets no credit in me liking photography, Ms. Hill made photography awful. BUT I did learn how to develop my own film and some other cool nerdy picture things in that class. In college, I mostly just took pictures of my friends so they'd have pictures to post on Instagram, but it doesn't matter what you like to take pictures of because in this age you can never have too many.
Here's why you can never have too many: they're easy to organize and you can scroll through them. The primary format for picture-taking is digital, so if you run out of storage on your SD card you can put them on your computer, and if you run out of room on your computer you can put them on an external hard drive. You can also dump them all into folders by year so you can find them easier.
Beyond all that, the reason you can never have too many pictures is that you would rather have an insane amount than too few. I would rather be an old lady in a rocking chair spending hours trying to scroll from March 2018 to April 2018, than to not have enough pictures to reminisce with at all. Someday your pictures will be relics of an ancient time. Children will ask you what it was like when you grew up, and what your hometown used to look like, and they'll want to see pictures of cool things you did. Hiked a mountain? Take a picture of every tree. Made a cool art project? Take a picture of that too. Eating some really great food? You can take a picture but please don't share it, everyone in the future still has sushi...it's not going anywhere.
Just take some dang pictures. You don't know you'll miss a moment until it passes, and you're more likely to catch your friends doing hilarious things if you always have your camera out.
