The relevance of the past to decision-making depends on the situation, but generally, the past and present are different. What was effective in the past may not be so now, so relying on past experiences for important decisions could lead to failure. Take marriage, for instance. Today's marriages differ significantly from those fifty years ago, with shared home responsibilities, both partners working, different hobbies, and shared parenting roles. Entering a marriage with a 1950s mindset today would be a surprise. Times have changed, so a modern approach is necessary.
