New instructions

When you move to any new way or working the new way takes longer than the old way.
There’s no muscle memory.
New instructions are complex.
What was natural is alien.
So it’s comforting and compelling to slip back to received practices.
Particularly when the going gets tough. That might be ok. Expediency counts. Doing the right thing for someone else sometimes means doing it the wrong way, even when you know it will set you back on an agreed path.
So you give yourselves a pass.
You let it slide.
That’s ok.
It’s a weaning process. There will be mishaps and emergencies. The point is to win the long game. At the beginning, go easy, and give yourselves a break. Over time, tighten the reigns and allow fewer excuses. Build that muscle memory, internalise those skills, and remember the change is for a reason.
Skippy strategy: Build muscle memory.
