Once I was away from home and urgently needed to get some work done, so I borrowed a laptop from a friend for a few hours, since I didn’t have mine with me. His was a different model than mine, but still very similar.
For the first 20 minutes or so everything felt completely unusual. I kept omitting letters or pressing the wrong buttons, and needed to watch the keyboard to make sure I was pressing the right ones. But if you looked at the two keyboards they were not that different.
We are capable of making such fine tunes to our actions and habits that even the smallest change can get us off track for a while. But at the same time, we are capable to adjust to the new in only a few minutes.
As fast as we develop our habits, we can also change habits. We only need the will or the necessity to do it.
