After writing "Don't give up" I felt like giving up. I stopped submitting to dreamstime, but not due to lack of confidence. It was due to some unforeseen circumstances. Now I'm able to continue what I began, create and submit.
However, I stopped when I felt like I was starting to get a grasp of both pieces of software. So I opened up photoshop, spent a little time on a nature photo that I was pretty happy with and it was rejected in a very quick fashion. I read the comments and took in what the reviewer said. Some of which I honestly agreed with. But that rejection really helped me.
How did this help me? It reminded me that as powerful as photoshop is you still need to put your all into your image. Pure talent is great but pure talent with direction and motivation can be amazing. Yet I forgot that along the way and it's funny it took that rejection to remind me of that. It also reminded me not to shy away from Adobe Illustrator.
I'm not in any way saying I enjoy rejections, I'm saying I now use them to motivate me to get better.
