You don't need to hoard ideas

[I have published a book called "Goal Achievement Power"! Please check it out if you'd like!]

I am asked this occasionally, but I don't take any notes on book ideas at all.

I am asked this occasionally, but my answer to "How do you come up with ideas for books?" is that I intend to write about things that I want to write about and that others seem interested in as well.
For my novel, I made it "100% the author's own" to a significant degree.
I think I write at least one sentence directly into the manuscript. I write things like, "Wedding preparations are like a school festival, which is interesting."

You don't need to let ideas sit

This is something I really want to tell myself, but I think you don't need to let ideas sit..
Once you think of something, you should just create it immediately. Of course, you should give it your all at that time. There is not much point in doing it half-heartedly.

Create it with the maximum power you can exert at that moment

You should create it with the maximum power you can exert at that moment, bring it to completion, and just put it out there. I believe that repeating this process is the best path for growth.

If you give it your all, it's fine if it's a dud or if it flops

If you give it your all, it's fine if it's a dud or if it flops.
If you are going to make a mistake, it feels better to make it while giving it your all. It is cooler to make a mistake openly than to try to clumsily cover it up.

Conclusion: Put out what you think of as much as possible

If you put out what you think of as much as possible, using all the power you have at that moment, I am sure your life satisfaction will be 5 stars.
