I love this point and I've repeated it so often over the years to friends and colleagues who end up at this point. A good forcing function is to always ask, when you're getting a new tool, whether you've exhausted the capabilities of your current setup. It's hard to be honest about this, but consider what skilled practitioners can do with lo-fi equipment, and you might find it'll force you to re-evaluate what you can do with yours.

At a certain point, I stopped looking to new gear (as it pertains to music) and started focusing on trying to push the boundaries of what I had. As it turns out, I wasn't anywhere near close to pushing what I had to its limits, which proved I should just focus on technique and craftsmanship. Since then, I've grown a lot more.
