If you’re an Ideator, present your ideas and let someone proofread them

Whenever you come up with an interesting idea, write it down.
Try to be as detailed as possible.

Work on that idea until you can completely present it.
For example, if you are working on a story, make sure it has all the elements to be considered complete.

Once done, make a concrete presentation of your idea.
It could be through drawing pictures,  using analogies or metaphors, or simply explaining your concepts step by step.

Find a trusted friend or colleague who can proofread your ideas and identify potential pitfalls.
If you don’t have someone to listen to your idea, try looking at it from another person’s perspective. Then, make necessary changes.
