In Egyptian Arabic, the word 'insan' means 'human'. If we remove the 'n', the word becomes 'insa', which means 'to forget'. So you see, the word 'forget' is taken from the word 'human'. And since it was God who created our minds and hearts, He knew from the very beginning that we would quickly forget our history, only to keep repeating the same mistakes over and over again. So the ultimate test of every human is to seek wisdom. After all, wisdom is gained from having a good memory. Only after we have passed this test will we evolve to become better humans. Man is only a forgetful mortal, but God — He sees, hears and remembers everything.
Every end of every day is the most important time of that day because you confront with your past and you obtain a chance for tomorrow not to repeat your past mistakes!
