Think about death. You do not know how much time remains to you. And remember that if you do not become different, everything will be repeated again, all foolish blunders, all silly mistakes, all loss of time and opportunity - everything will be repeated with the exception of the chance you had this time, because chance never comes in the same form.You will have to look for your chance next time. And in order to do this, you will have to remember many things, and how will you remember then if you do not remember anything now?
