We've got a long-term plan to head down that way in a couple of years, when my daughters a bit older.
Getting the balance right is a lifelong task I recon. You're not going to regret following your dreams. Careers are over-rated IMHO. I've just escaped from a job which was challenging, mostly good, but was expected to put in stupid hours. Doesn't compare with now when I can ride to work, see my family + mates loads more, live within 5 mins of great mountainbiking, and get to sly off to the coast loads more regularly than I could. Lifes too short. You know how right it feels having a good session in the water. Better to have that on your doorstep than constantly on your mind in a landlocked career-job.
