Sound advice I agree, but not everyone has the time or ability. While these guys may be after a buck, surely that is why we all work.
I definately would not suggest following anyone blindly, do your homework first, as in any field there are loads of dodgy characters out there.
At the end of the day if you want someone to fly your familly from A-B, you get a pilot, preferably one with an ATPL and some experience. If you want someone to look after your money then get someone with equal quals and a track record.
Far too many stories of guys doing a fast track course in finance and then thinkng they are experts.
