The weight of unexecuted ideas is often a much heavier burden than the ideas you miss by not storing them.
There is no shortage of good ideas. The bottleneck is our ability to execute them and the big assumption is that we know which ideas are good - we don't.
Plus, counter-intuitively, the more good ideas. you store, the less likely you are to find that one good idea again.
The very act of storing more good ideas makes rediscovery less likely.
Whenever you do something, it enables novel pathways which can result in more new ideas.
Good ideas come back, naturally. They linger and stay in the back of your head.
A good example: I have many ideas in my head for a next book. A few keep returning, because they excite me so much.
That's where I want go. No need to write all my ideas down.
I'm waiting till something really grabs me, and then I will seize that opportunity.
A long list of ideas is where good ideas go to die.
Don’t worry about not losing that good idea, worry about how you can get rid of those good ideas that are actually bad.
Good ideas come back! I also like reminding people about that.
