The word can't is a word that needs to disappear from people's vocabulary. It's an evil word, on so many levels.
But for me, the word can't is a challenge that my brain subconsciously accepts, for good or bad. If I hear the word can't, my brain goes, "Watch me!"
Most of the time, it's a good thing, because it's not about focusing on limits, but accepting that the solution on how to do something will be made up of strategies that might be a bit oddball. But everything can be done, even if we don't know how. However, there have been times when I heard that horrible little word, and I got myself into big trouble.
"You can't get lost." And it wasn't just a 2-hours drive in the wrong direction. I totaled the boss's car.
