You indicate in your first post that you can't travel an hour to do hillwork weekly, but don't underestimate what even just a few sessions on those hills will do for you. Even if you can't get down there weekly, it'll still be very much worth while to get there when you can. I live in a flat area and, when I was purposely training for out-of-state hilly rides/tours, I was only able to hill work here and there. That here and there helped tremendously though.
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
