Let’s tell a story.
I’ve got a Fujifilm X100s. It runs about $1300. It’s easily the best camera I’ve ever owned. I take care of it as best as I can, but I don’t let taking care of it impact.
When it dies, swap them all.
For me, the most important part of improving at photography has been sharing it. Sign up for an Exposure account, or post regularly to Tumblr, or both. Tell people you’re trying to get better at photography. Talk about it. When you talk about it, other people get excited about it. They’ll come on photo walks with you. They’ll pose for portraits. They’ll buy your prints, zines, whatever.
