Your making a great decision . Best of luck with the first trials. Is your wife on side as far as knowing what your doing ? Once you've made this decision it's best to keep on even if you have a stumble or after a while decide you can try again ! This is the place that made all the difference. Although the first push can be problematic it doesnt have to be that bad . If it is keep on better things are just around the corner. I cannot tell you just how much better my life has got and I thought my life was good before.
Keep here.
Regards John.
