Thanks but I'm a big boy and can take it. I know sometimes my ego gets me in trouble because of how long I've been doing this. Please answer these 2 questions. What is a hobbiest to you and how are you better then them?
It's not about you Mix. As a professional with nearly 30 years full time in this field I won't collude in the insecure pile-on of wannabe culture that permeates the DJ world.
I'm not better than a hobbyist - that's the point. What I have is better resources, higher risk tolerance, more skills and experience, and a track record customer's can rely on. Despite all of that - I still have to compete with the valid alternatives of kids with an iPod, and part-timers with a laptop. Not better or worse - they just are. I can take my advantages and apply them to jobs beyond the ability of these competitors - or I can rant and rave about how they are doing it
"all wrong" - which as you wisely pointed out has no basis in reality.
Advice is measurable. When someone has no real skin in the game their values will be skewed in directions which are dysfunctional to those who do, and their perspective on resources void of the pertinent immediacy.
Your notions about perfection are a trap. The fact is yes, I can make my every client perfectly happy every single time. That has nothing to do with what you, Canute, or even I would view as "perfect." There is no such thing as perfect or perfectly right. There are just perfectly suitable outcomes. I suppose if you want to know what makes anyone different - it's diversity, the range of circumstances and settings in which hey can make that happen. A lot of DJs, especially those on the sidelines tend to be rigidly one dimensional. What they've done is packaged something personally repeatable largely centered around gear, and seek out routine.
I can only guess based on your posts, but it sounds like you are of/or near retirement age, interested in DJing, and short on resources to acquire gear. The advice of part time mobiles (who function largely as gear collectors and haulers) isn't going to work for you. You need to recognize that your personal touch, commitment, and physical ability are the tools with the most potential for you. Stop following gear around and start leading with you - the DJ. You don't need gear to be a DJ. You don't even need music - you just need a place to to actually do it. That means looking for clubs/bars that need a DJ - not an audio system. Looking for entertainment venues and providers who are seeking DJs not gear.
