By definition. It’s your dream. How could someone else create it for you?
The scary thing is, just like any first creation, your first one won’t be great. You will create a job you think is perfect and find yourself a few weeks later realizing everything else that comes with your position.
Hopefully this happens when you’re in high school and you name yourself the president of the after school club you start. Hopefully this doesn’t happen when you’re 33 and you just quit your job to become an entrepreneur because you thought it would be a better gig.
Create a dream job early. When it’s low stakes. See what you like, what you don’t like and make the next one better. Start now.
