I watched a movie once about a guy who lost all his memory about his past.
He wanted to get back his memories at all costs.

When he found the man who took away all his memories, the man asked him:
"why do you want those memories back? they're not all good memories..."

he then saw a flash back of his life.
his wife cheated on him.
he was betrayed by his closest friend.
a memory of him dying.

He was staggered by the feelings brought on by those memories,
but then after a while he said...

"I'll take the bad... as long as I can take the good."
