All aspects of our lives are composed of relationships, including business, and none more so than entertainment.
All of your actions and choices reflect upon those relationships - building them, altering them, sometimes severing them.
There are more people asking for one's time an expertise than several lifetimes can fill. How on earth to choose which relationships to cultivate, which to stand on the sidelines for, and which circumstances it makes sense to walk away from?
The number one way I figure this out is: does this person need me? The answer, which you might think strange, should always be 'no'.
Let me explain. The people that I want to work with are talented and motivated in their own right. They don't need me holding their hand every step of the way, and will manage whether they have my assistance or not. They'll want to work with me because our sensibilities mesh well, we share a goal, we can help each other.
I have both personal and professional friends in this category that I'll go out on a limb for, go the extra mile every time because I believe in them just as much as they believe in me. We do great work together. But if I were hit by a meteorite tomorrow, their projects would move on, whether I'm there or not.
That is the person I want to work with. These are the people that I'll fly across the country for, that I'll volunteer time and effort to help.
The other sort, are the ones that like the idea of fame and fortune, rather than the process of making something. They expect that merely knowing someone who works on films is enough to make them a famous actor, a top tier writer, whatever. (These are most often the strangers that want you to work for free, too!) Somewhere, they think making films is like playing lotto, at whatever stage. Some have the 'great idea' that's been floating around for a decade, unwritten. Some have even gotten to the 'made a movie' stage, but didn't realize how much time, effort, and expertise goes into one until it is far too late.
I suspect you have friends like this too - 'I could write a novel, if I only had the time', 'I have this great idea...', 'I could be an artist/graphic designer/pro blogger but...', and a slew of others.
I'm not a pro blogger (obviously). I have no one to blame but myself for the unwritten words to my novel. I'm not really an expert anything - that's right, I'm NOT an expert. I do share observations on life and work that have worked for ME. They're designed to be helpful, so hopefully I can save you some of the heartache that I've gone through on my path. That's all.
