Who am I? What's the point?

Sometimes I wonder what I am doing with my life. I work to pay the bills, to allow me to live in a nice house in order to... work to pay the bills to allow me to live in a nice house in order to... {and repeat recursively till dead}.

I sometimes lose track of who I am with the two lives I have - one in Shetland, and one in Lancashire. The Shetland life is clearly defined - pilot, trainer, mate to those around me. The Lancashire life is less so - I provide, I support, I... walk the dog...

Bit weird. Sometimes I just wish I lived in one place. The transition periods between the two locations mess with your head.
