Younger people who attend us customers from behind a counter will often ask, when ready to attend you, "Are you right?" I find it very difficult to not reply "The customer's always right! Just confused."

If anyone asks that rhetorical question "How long is a piece of string?" I'm routinely tempted to answer "Double the distance from one end to the middle!"

When asked by someone "How are you going?" I have several stock replies, depending on circumstance;
"Gently!" often gets a nod of appreciation, as 'different',
"Never a dull moment!" ditto and most frequently truer than the first response,
"Can't complain! ....... But I'll practise if you like; they say practice makes perfect!"

"No guts, no glory" brought to mind the novels of Mary Grant Bruce, which I had a minor acquaintance with during the 50s due to my sister; don't take the suggestion as gospel though. When faced with similar decision-making I've said to myself either
"Faint heart ne'er won fair maid!" if I've some previous exposure to the consequences, or
"Try anything once!" if I haven't.
