Beautiful sights always trigger my desire to photograph them. But I do sometimes make the decision up front to not bring any cameras with me so that I could just live the thing and preserve it only in memory. Or just observe and let go. Still memory would keep it, of course.
And I do realize photographs are for sharing. Be it on social media or with select few years after... why take them if not to make them tell the stories...
So, the other option occurs when I get tired of others and care not about future use.
That is like sleeping. It helps the mind rest and recreate itself.
