Be mindful
I think that's the most important point. When you don't pay enough attention to your actions, that's when things can easily go wrong.
Very often we go auto pilot on daily chores and don't give a thought about the process. Locking the car after we get out is one great example. There's been a few times I ask myself have I locked the car, and run back to check only to find I have locked it. All because I'm on auto pilot, I don't even remember I have pressed my key fob to lock it.
Just out of interest, how long did it take to get the ink off your hands?
