Do not tell your friends about your nascent idea, your notion, the area you hope to explore next.
Do not seek reassurance from them.
Do not become vulnerable about your tiny new sprout of an inkling.
It will be extinguished by people who mean well. They are trying to protect you from heartache.
There is a very, very tiny group of fellow travelers who can amplify your inkling. For the rest, keep it quiet. Trot out a make-believe idea instead, a pretend Potemkin Village of a project, let them dump all over that one instead.
Keep the other one in the incubator for now. There will be plenty of time for sharing later.
