Ever feel like the ties from the first half of your life fall away pretty quickly while you're forging new ties for the second half?

I always thought life was more linear and the things/people in your life would remain the things/people in your life from beginning to end. Personally, that's not the case. Everything has changed, some for the great (my job) the rest is transitioning to something I don't quite see yet. Regardless, the second half of my life is radically different from the first.
