It's always around. You just don't see it.
You always end up with too many pictures to edit and too few that you feel 'got it'.
Since the background is as important as the subject, you mustn't let it default by chance. You must control not only vertical and horizontal, you must be aware of the depth of field (or lack of it) that you want in the background.
Always shoot it now. It won't be the same when you go back.
The pictures are everywhere. If you're open, they will find you.
What you're shooting at doesn't matter, the real question is: 'Does it give you joy?'
