When you have an expensive camera or you put a lot of time into a project, it can easily skew your ability to be objective about the results. It's important to not allow that to happen.
Coming to you from Ben Horne, this great video examines the idea of effort versus results. It's important to always be able to step back and look at one's own work objectively, but that can often be clouded by the amount of effort (or cost) that has gone into its creation. After all, it can be frustrating to put a large amount of time into the creation of something only for the result to not seem to justify the effort. The simple truth, however, is that sometimes, our best ideas come from fleeting moments or five-minute experiments, and other times, those hours spent toiling away might not amount to anything worth keeping. To grow as an artist, it's crucial to be able to let go of the need to have a predictably proportionate relationship between the amount of effort you put into an idea and the results you get from it. You'll feel much better and grow more having done so.
