You can’t sit around waiting for a good idea.  So you just have to take the first good idea that comes to mind.  And hope it is good enough. 

Two kinds of people:
Those that things happen to.
Those that make things happen.

If you are the kind that wants to make ideas happen, here is how. 

Brainstorming is a good way to make ideas happen.  But it takes special arrangements.  You may need need an alternative that you can do fast and by yourself.  Something that you can try out without a big production. 

In this venue, we give suggestions on how you can do that.  These suggestions adapt brainstorming methods to the goal of prompt and private.  Technically, this process is called ideation.  That makes it sound important. 

First, the most important rule in brainstorming:

1.  Do not evaluate while you are looking for ideas.   

If you decide that an idea is bad, you will not only kill that idea, you will kill all the other ideas that it might have led to.  If you decide that an idea is good, your brain may think its job is done. 

2.  Write a question that asks how to do what you want to do.

4.  A good idea is one that suggests other ideas. 

The way to have a good idea
 is to get a lot of ideas to choose from.

5.  Don’t try to organize till you think you are running out of ideas.

6. When you are about out of ideas, organize your ideas. Put similar ideas together.

Look at each group of similar ideas. Ask if there are other ideas like these.

If anyone asks, you are making a taxonomy of possible solutions.   That will probably end the conversation.
