ELI5: Once you have an idea, how do you get it into production?

IE. investors, app development, protection from others blatantly stealing your idea?
gpt
1. Have money to invest in the idea
2. Find other people to invest in the idea
3. Legal costs to know if you're actually the first to have the idea
4. Legal costs to patent idea
5. Make more business contacts, potential customers
6. Finding a manufacturer
7. 100/0 split on costs & profit for you & manufacturer **or**
8. x/y split on costs & profit for you & manufacturer
9. Realize you have no business plan 
10. Make more business contacts & start begging
11. Find a new project
12. Sell out & be rich **or**
13. Accept failure & the $100k you threw into the money pit

You cannot stop someone stealing 'an idea'.  Ideas are free, always.  You need a 'something' to protect & get the right legal protection for.  If you have a great idea and don't know the industry you think would benefit the most from the idea, your only hope is to be really lucky because if you don't succeed immediately, someone else will solve how to work around / improve / undercut your idea.
