The seeds for ideas are everywhere: in everything you see and hear and touch and feel. Combine this seed with that seed, and off you go.
Above might look like "a bigga mess" on the deck.
You look closer and you see nuts.
You kneel down and look closely at one of those nuts:
Pretty interesting thing, that little nut. Wonder what's inside?
Chop it open. Huh. Who might want that nut?
Ah, my nosy friend, the squirrel.
And your mind is off and running. Where is she taking that nut? What does her home look like? Does she have a family?
No, I don't normally write about squirrels, but I get my story ideas the same way. That crowd of people over there - look at that one boy - look more closely - what's in his hand? - where is he going? - who are his friends? - what's bothering him?
Off you go . . .
