|Fred was having trouble with a drinking problem and swore that he would correct it with sheer willpower. He had decided to walk straight past the pub without going in.|
As he approached the doors he kept repeating to himself, "You can do it. You can do it."
The pressure was tough, but Fred persevered, right past he went.
Fifty metres past and he congratulated himself, "I knew you could do it. You were great! Let's go back and I'll buy you a drink."
