2. The Forgetful Con Man
Once upon a time, there was a old con man. He had two identical twins, Anthony and Alex, both of whom were very rich. They didn't know he was a con man.
This con man was very forgetful. Whenever he was going to do something, he would inevitably  have forgotten it unless he wrote it down on his reminder board.
Now you have all the information, here is the puzzle:
One day, the con man had to make a very hard decision. After much thought, he decided, "I'll do it." Hesitantly, he wrote a reminder on his reminder board. Then the con man looked at the reminder, and realized he could rewrite it to save space on his board. So he erased the reminder and rewrote it.

Here is what he wrote. What was he going to do?

Hint below.
