This might sound odd but I get less social phobia when I cast people as things.
Often people ask how you are but they don't really care about what answer you give.
If I imagine them as a piece of complicated machinery I can simply concentrate on using them to whatever end I need without getting into the complexities of how they work.
People I regularly care about I try to treat as people but its not easy even then
Does that make me some kind of selfish person ? I hope not.
Absolutely correct and, I see nothing wrong with that so long as the few you do actually have personal relationships with are people when you aren't working.
On stage, in the office or, studio, even my friends become tools of the trade, right there with the sound technicians, the choreographers, lighting team, agents, managers, security, etc... When it comes to my career, I don't care if you are some form of divine being, if you are there to do a job, you are one of the tools I need to do my job.
Most stay in the thing box since I only interact with them for work reasons but, I do have friends in the industry, though we don't usually perform together. Mostly my choice, makes it too hard to shift from person to thing and back again too often. DJ is the exception but, only because he does the same thing. When we work together, we are both tools, things the other can use to get the job done and, use as we need to without worrying about feelings.
That's how it works best in any career, workers are tools, things the company or business uses to get the job done and, we all should be treated as such, used to the best of our skills and abilities in our careers, and using others where we need them. it isn't personal, it's work, success and, it is one thing that separates the ultra successful from the peons.
If you take emotions, personal feelings, like or dislikes into consideration, you probably won't assign the best skilled person to a distasteful task, especially if you like that person but, forget all of that and, make them a tool, a thing for you to use to get a job done, an object without emotions, needs or preferences and, you assign the best person to the task. They might hate it, might quit after it's done but, you got it done the best it could be done. You can replace that tool later, so it broke while doing the job, get a new one tomorrow.
Yes it's cold hearted and, it sucks to be on the receiving end of that kind of treatment, but receiving it helps you learn to give it and, that leads to advancement and success. I've been on both ends, still am but, I accept being the one being used to do a job because I understand why those I'm working with need to treat me like that, they want to succeed and, when they succeed, so do I.
In the end, it's selfish, even if I am the one being used, I'm allowing it because I need my agent, manager, promoter or, whoever to succeed so that I can also succeed. Ultimately I'm fueling my own success and, even if it has to be cold and impersonal that's how the best get to top in any career.
