10 ways to come up with those last few ideas (if you're stuck at 6, 7 or 8 ideas)

Take one of your existing ideas and subtract something. Could be money. Could be time. Could be resources. How would you make that same idea happen but without money? Or on an accelerated timescale. Or without anyone to help?

Take an existing idea and then figure out how you might scale it. What would you do? How would you make it work so that it is working overnight (i.e., without your involvement)?

Take two or more of your ideas and combine them. What happens? For example, take the idea of idea subtraction and idea multiplication - what can you subtract and then how could you scale?

Not as useful as idea subtraction because you're trying to work with fewer resources, but sometimes it can help you get unstuck. What would you do if you had infinite money? Infinite time? Hundreds of bots that could do repetitive processes for you?

Take your same idea and consider it from another occupation. How would an artist approach this problem? A mechanic? Engineer? Computer scientist? A math teacher?

What would Richard Branson do? Mark Cuban? Leonardo da Vinci? Sometimes thinking about it from someone you admire gives you ideas

Flip to a random page. Read about the tactic. Then see if that same tactic would apply to the situation you're trying to come up with ideas for. If not, repeat with another page or another book.

Similar idea to flipping to a random page in a book, generate a random verb. Does the verb help?

Imagine you had a genie and you could wish for the best solution. What would it look like?

Sometimes starting from the worst solution can be a great way to get unblocked. If you don't have to worry about your idea being bad (because you want the worst solution possible), you can usually generate good ideas.
