There's another way of looking at all this....
What do you do for pleasure/relaxation now? You're not on the breadline, so presumably it costs money. I assume that on at least one day off a week, you go out and have a good time. Maybe it doesn't cost quite as much as an hour's helicopter flying, but it costs. And have you ever worked out what that costs you over a year? I bet you haven't.
So, now assume that you'll do an hour's helicopter flying a week, for around a year. During that day, as well as flying, you'll drive to the airfield, check the weather, learn a bit of theory, chat to people, look at helicopters, etc etc. It'll be a fantastic day which you'll look forward to all week - if it isn't, pack in this whole idea now! And after you've got your PPL(H), you'll do the same thing, although maybe marginally less often, and it'll cost you a tiny bit less per hour. After all, if you're not going to do that, why bother to get a licence.
So, do you have the time, money and inclination for helicopter flying to become a part of your life in this way? If so, why does it matter how many hours it takes you? If not, forget it and go take up golf or something!
