The strongest fences are the ones we never run into.
An enclosure doesn’t need to be high once the animal has learned not to test its boundary at all. Eventually a low fence is enough, then a line in the sand, and in the end only the memory of one. We humans are not so different.
Habits, expectations, and routines mark off spaces that we take for the whole world: the career we chose and never questioned, the opinions we adopted, the money we invest along familiar lines. As long as we move within these spaces, we feel no resistance, and we mistake that calm for freedom. The boundary only becomes visible when we dare to take a step in a direction no one had in mind for us.
That is when we find out whether there is really still a fence there, or only the habit of believing in one.
Not every fence has to come down. Some protect what matters to us. But every one of them deserves to be seen and tested at least once.
