It's not what you think. David's 10 upgrades have nothing to do with gear. As he says:
Want better photographs? Of course you do. We all do. But it’s probably not our gear, or lack of it, or how old it is, that’s standing in the way: it’s our excuses and lack of creativity.
Make this the year you never once blame the camera. Make it the year you embrace whatever constraints the gear (or life) presents you with, and then get to work. Work around it or work with it. But work.
The gear you have is enough and probably will be for quite some time. Upgrade the photographer instead. It’ll be cheaper, less frustrating, and here’s what matters: it’ll be the one upgrade that changes both your experience of photographing and the photographs themselves.
Instead of talking about gear, David's 10 upgrades are about "upgrading the photographer" and making changes that will improve your photography regardless of what you are using. Ten upgrades may be a long list but the key, he says, is to pick one and enjoy the "freedom of doing that" instead of panicking about whether you need something bigger or faster or newer.
Ah, these were words I needed to hear. I'm not yet sure which upgrade I will focus on but I'm looking forward a new challenge. Thanks, David!
