Wisdom, experience and knowledge are similar but they are NOT the same. Knowledge is facts that are taught and learned. Experience is knowledge gained first-hand. Wisdom is experience, combined with knowledge, over time. By advising someone that "gear doesn't matter," you're trying to instill your experience and wisdom into someone else as knowledge. You believe you're saving them from the frustration and cost of experience when in fact you're robbing them of it. Even worse, it's hypocritical to advise someone to "go out and shoot," to learn through experience, but then try to rob them of that very experience when it comes to purchasing gear. You can't play the blues convincingly by observing someone else's heartaches.
It's been 3 years since I've gotten back into photography and I wanted to reflect on what I've learned in that time. This is just the first of a few items I'll be touching upon. I wish I'd bought the right camera the first time. I want to address the abundance of Youtubers who often, and loudly, try to talk their viewers out of upgrading their equipment. The line often goes, "instead of upgrading your gear, thinking it will make your photos better, invest that money into education," and then they rattle off the names of affiliated Youtubers who sell online education courses on photography. Realize that this recent trend is wholly self-serving and not in your interest. There are of course those who are so affected by marketing that they believe a new camera will improve their photography but either can't see, or won't admit, that their results are from a personal, and not a technological, deficiency. However, those types are far fewer than these Youtubers would have you believe. More importantly, if you value education, I implore you to seek out a reputable photographer that teaches photographic techniques rather than some nobody whose only reputation is a trail of instagram posts. Just because they charge for their videos doesn't mean they're credible; in fact, your local camera store or public library are 2 places where free, or low cost, but highly valuable sources of education is offered on photography.
