> There is a french say I like. If you need to cut a dog’s tail, don’t cut an inch every day, chop the whole thing quick

Well there’s cutting off the dogs tail, and then there’s accidentally cutting off your own fingers in your haste to get the dogs tail.

There is another saying:

Slow is smooth and smooth is fast.

Act quickly when needed but not so quickly that you don’t have time to assess. You should know what you’re cutting before you cut.
