Investing in any area tends to be difficult, no doubt about it. It requires a lot of reading, searching, research, re-reading, seminars, and math. And then you have to build up contacts and do a little travelling. It has taken me a good year to set up for it. Still, I think that it is definitely worth the effort though.
And if properly set up, you can have a salary of $200k but have the tax footprint of $50k or even less.
