Be gentle to all and stern with yourself.
Only the educated are free.
Problems are not stop signs, they are guidelines.
Do not weep do not wax indignant. Understand.
If you can dream it, you can do it.
The wise does at once what the fool does at last.
I can, therefore I am.
Leap, and the net will appear.
Know or listen to those who know.
Be kind whenever possible. It is always possible.
Sometimes they are a matter of luck the photographer could not expect or hope for them. Sometimes they are a matter of patience, waiting for an effect to be repeated that he has seen and lost or for one that he anticipates.
