I agree that one is usually concerned with more recent information (hence the effectiveness of the LRU caching heuristic). However, looking back at past endeavours has been a source of new ideas and joy (reminisce achievements) for me. I don't do it frequently though. Maybe once a year or once every two years. Revisiting your past serves as revision as well (you get to see concepts you once used in your work/life).
