I'm starting to think that I won't get a factory job.
Is there a reason why you don't want a factory job?
You can't become successful if you work at a factory
If you don't want to do a certain job then don't do it. You're allowed to make the choice of what style of work you want to do. No one has the power to force you to do job that you don't want to do.
It's fine. I'll be successful with my business idea.
That's fair, and I hope that you have a lot of luck with your business idea. I am sure that it is a good one, and if it doesn't work then maybe you could try out that factory job!
