People usually escape from their troubles into the future; they draw an imaginary line across the path of time, a line beyond which their current troubles cease to exist.
The quote from Milan Kundera's "The Unbearable Lightness of Being" reflects the common tendency of individuals to avoid facing their current issues by projecting themselves into a more hopeful future. This escapism represents a psychological mechanism where people envision a time when their difficulties are resolved, providing them comfort in the present moment. It highlights a human desire for relief from the weight of present burdens.
