A few years ago my wife asked me to attach some tubes to the wall. I noticed that there was little room for a wrench. So I used a ratchet wrench as shown in the picture.
There is an unwritten rule to use a wrench for a nut and a bolt.
There is no rule for the type of wrench.
Proof in the pudding
In the kitchen one of my kids was stirring in a pan:
“30 seconds should be enough, but I think it is not enough.”
I stopped with my actions:
“Is that not long?”
“Last time it went all right.”
I tried to remember the taste, the structure, and the smell of the dish. But I had only positive thoughts.
“First you follow the rules. Then you must change them.”
“Must?” was the reaction.
“I mean: if you think it will make things better.”
“Your boss will not be happy.”, my kid remarked.
“If you stick to the rules, then you will not become better than your teacher.
Otherwise everything will remain the same.
Not all experiments will go right, so you need some room.
My boss is also experimenting:
“I have this product.”
Customers will give feedback:
“We would like to have another product.””
