There's no such thing as a painless lesson,
They just don't exist,
Sacrifices are necessary, 
You can't gain anything without losing something first,
Although,
If you can endure that pain,
And walk away from it,
You'll find that you now have a heart strong enough to over come any obstacle.
Yeah,
A heart made FullMetal. 
- Edward Elric, FullMetal Alchemist Brotherhood.
