Affiliate Marketing Secrets

I just got offered a position and this legal clause sounds like anything I make, for the company or on my own becomes the companies property. Is this true?

I was wondering the lists of jobs/careers that will pay 100k/year after around 5 years of experience not including the schooling. I’m fine with going to school for 4-7 years MAX, would really prefer not to go to school more than that. I’m 21 (just turned 21 two days ago) and I have not been to college yet. I do have my high school diploma but a very poor GPA. I’m not stupid but I did have a hard life. I didn’t make my life hard for myself by partying and drinking but it involves more with parents/etc. I don’t mean to make ‘excuses’ for myself but life does have extreme difficulties that I couldn’t avoid and that’s just the way it is.
I grew up in a poor home, been homeless a couple times and didn’t have a lot of anything so I would love to change that for myself and my family and my future family.
I’ve done some research and I first was planning on becoming a psychologist. I couldn’t handle that though, I don’t have tough skin and I couldn’t ‘handle’ other peoples problems. I have enough of my own. Then interior design, I don’t have the niche for it I don’t think. Then computer science but I know I would hate doing that for the rest of my life.
So, besides those and besides anything to do with dentists, doctors/nurses and sales I was wondering what else pays around 100k/year, with around 5 years experience(not talking about right out of college) and 4-7 years of college(any Colleges you recommend in Illinois?).
Thank you all for your time!
P.S. I love inventing things!! I have around 10-15 inventions that are currently not available, but I did not check if it has already been patented though. How do I do that without a big rich guy/corp. stealing it? I know patenting sometimes isn’t the best way to go.
