It’s relatively easy to write down a list of 10 ideas.
I know, because I’ve had a lot of practice with this.
What’s not so easy is to choose one, and execute it consistently.
That’s why your ‘great idea’ doesn’t need to be a secret.
No one is going to steal it and make millions off of it.
Your idea, or at least a version of it, has been thought of before.
By itself, your idea is worthless.
It’s the action you take on it that holds all of the value.
