POST CODE

I wonder if I'm post code Can anyone even know The journey it's felt so long I wonder if it's now gone In life you outgrow old shoes And so many things you don't use But you don't stop walkin' You don't stop walkin', no I babbled before I spoke I slept long before I woke And started walkin' So many times I've mastered a set of rules to help me guide my way So many times I've grown up to find that some rules don't stay A cast once repaired my bone My income was based on loans But somehow in life I grew And somehow I think I knew That of all the gifts that our Father has blessed us to enjoy sets us free But in freeing ourselves we are loosening up ties that once made us me If Da Vinci just kept the road Mona Lisa would be untold While he just kept walking While he just kept walking But it takes some daring And I'm frozen staring Do I just start running Do I just start running Do I just start running Do I just start running I wonder if I'm post code I think so, but I don't know Do I just keep walking
