I'm not so good with sayings and stuff, but try one of these:
1. If you can't beat 'em, join 'em.
2. Live by the sword, die by the sword.
Here's another few:
1. Something's rotten in the state of Denmark.
2. This is my son's village. We are deep in the mountains, and the winter is coming. You cannot escape.
" The secret is to just keep moving."- Franka Potente, actress
" All the world is a stage." - Jacques, As You Like It by Shakespeare
You learn things about who you feel you should be but then you see these things are not you at all.
