Where does inspiration come from

Was feeling , uninspired , to capture a blip today. Was sitting there taking a quiet moment, looking out the door at the Kermadec Pohutukawa, resigned to the idea that there would be no blip today. The brain just switched to monochrome, without me asking it,  and the late afternoon light just made the foliage glow. Didn't have a choice really. You just got to do it.
