You can't make the same mistake twice.

You can't make the same mistake twice. The second time you make it, it's no longer a mistake, it's a choice.

 Learn From your past and go ahead to the future. If you have done the same wrong thing twice that means at the second occurrence you already have the #knowledge of your 1st mistake and you have chosen the same wrong doing 2nd time. Update yourself from the first mistake so that you don't have to face the same unwanted situation again.
