Break A Leg

As I age in a cage of a Mage 
And I notice a lot of advice 
That I heard as if it absurd 
Which I thought was metaphor 
Really I should take literal 

Like - "break a leg" - so then 
I could no longer try going in 2 
Directions - can't even if I want 
Physically incapable - downside: 
I have to hop to wherever I go
