The Last Window (1979)

Original title: Последниот прозорец

If one does not approach every problem carefully and patiently, the failure is inevitable. The view through the window that offers nothing, if one does not wait, is another story about a man who does not have the patience to study the problem in detail and calmly for which there was a real solution. Because after a hasty step, of course wrong, that same window offers a different view. The blank wall is no longer there, of course only the one who knows how to approach things studiously and who knows how to be patient and calm can see that.
