It's really not about the rejection or sales, nor is it about being a bit narcissistic. It is about who decides what is good and not good. Are they capable of making that decision? Well obviously, since they have the job they are doing, but we may not agree, so keep trying.....and forget what they think. My photos, sound, video clips won't make or break Stock companies or myself.A few examples I have learned over the years and not photography related, but life in general.
Did George Lucas sell Star Wars immediately or did he get booted several times, but did not quit! If he quit, we would not have Star Wars and maybe he would have settled building sets. Doesn't matter if you like or dislike Star Wars, it's the point!
I wrote a script about 10 years ago and got thrashed on every screen writing table site, every international screen writers site you can imagine. I found an agent who decided to take on my script and promote it, after about two years he said to me "nothing more I can do, however, don't give up". 4 years ago, I sold my script for a ridiculous amount of a lot of money, not the $2 million, Abrams sold Forever Young for, his first script for but not far off. Will it ever become a movie? They say chances are not great, but possible.
If you think you have something good, keep at it! Don't listen to the buffoons who do nothing or talk a big show or think they know what they are doing because that is their job they were hired for.
And by the way.......Not whining or complaining, not being narcissistic, just making a point I hope someone can learn from and thrive!
