Most people don’t consider their dream job, because it may seem impossible. They usually choose whatever job is available to them at the time, the ones that seem possible for them to get. They might think “Ok, I can do that”, and then apply for that job.
But I’ve come to realize that anyone can get their dream job, even if it seems impossible, if they consciously and purposely direct their life to get it. Achieving something that seems impossible usually is not easy, but the secret is to point your life towards that direction.
When I was young, I didn’t really think that it was possible to become a Disney artist, even though I loved Disney. I was talented at drawing, but when I look back at my work in art school, it was not very good, so I didn’t get much work in the beginning of my career. Even though my work didn’t really demonstrate success, I did have a direction, and I kept at it. When you keep at it, you find little ways to improve along the way, and that’s what helped me to eventually get work from Disney.
It may take time. It took me 10 plus years, because I wasn’t very serious about it at first. But because I at least had a direction, and I didn’t give up, my dream job eventually happened.
