Certain temperaments respond to anxiety by pulling inward. Their instincts tell them ' Don't go out to meet the world - you'll have a panic attack. Inside is where safety is.
War is chaotic and when you start having a larger scale film and you have a lot of safety protocols and choreography, I would imagine it becomes more difficult.
If I was wrong in yielding to persuasion once, remember that it was to persuasion exerted on the side of safety, not of risk. When I yielded, I thought it was to duty; but no duty could be called in aid here. In marrying a man indifferent to me, all risk would have been incurred and all duty violated.
I am distinctly opposed to visibly arrogant and arbitrary extremes of government--but this is simply because I wish the safety of an artistic and intellectual civilisation to be secure, not because I have any sympathy with the coarse-grained herd who would menace the civilisation if not placated by sops.
If you understood a business perfectly and the future of the business, you would need very little in the way of a margin of safety. So, the more vulnerable the business is, assuming you still want to invest in it, the larger margin of safety you'd need. If you're driving a truck across a bridge that says it holds 10,000 pounds and you've got a 9,800 pound vehicle, if the bridge is 6 inches above the crevice it covers, you may feel okay, but if it's over the Grand Canyon, you may feel you want a little larger margin of safety.
