You have to admit, it's a guilty pleasure buying new stuff. Sure, it sucks having to shell-out moola for the really good stuff, but if you are a legit working professional in your field, it's a necessity. BUT... as much as you hate seeing a series of zeros in the price tag of pro-level equipment, there is a part of you that is super happy about clicking that "buy" button. Photographers are notorious gear freaks, always lusting after the next biggest, faster, meaner piece of equipment, whether it is a lens, camera body, general accessory, lighting, or computer equipment. We live in a world that is now obsessed with efficient, lean business workflows. On top of that, society in general is always looking at how they can get services and products cheaper, faster, and easier. The same applies to the career field of photography. If photographers are expected to keep their prices lower to stay competitive, they have to find ways to make the price they are charging economical to keep their dollars per hour up at a desirable range. Ex. if you charge $200 for a photo shoot, is your total time invested into that project 3 hours or 30? If this (photography) is what you wake up and do every day, it is a prime example of a high output workflow. By that, I mean it's not like you are dealing with something on a small scale, like selling cars. You are most likely pumping out photos in the thousands every month if you have a healthy business. So, we are dealing with units in the thousands per month. Don't you think that is something that is worth evaluating, in terms of process workflow and where bottlenecks might be? Just like any other profession, the longer you keep at it, the quicker you are capable of doing a job, managing the juggling of processes, etc, and hopefully the lack of efficiency in certain spots will become more evident. You'll most likely continue to reach new levels in your knowledge and experience, and your current gear and approach may begin to keep you from breaking through to the next step. That's your cue to do something about it.
