Here's a little tip that I just recognized today. Look up all the business/entrepreneurship organizations you can, go to all of them. In the average big city, you'll find a couple groups where they complain about why bad things happen to them (inventor clubs strike me as tending towards this), you've find some dead clubs where nothing is happening, and you'll find clubs that promise you fame, friends, success ... in the exchange for something.
But then you'll also find a hand full up clubs where people aren't complaining and where things are actually happening. Furthermore, (and this is how you can tell you've found the right groups) there will be overlap in the membership of these clubs because the members will have already done their homework too. So, upon finding these, you have found the people you need to be friends with... the next step is to actually make friends with them. The best way to do this, of course, is to offer them something that they need but can't attain easily by themselves (I'm learning web design). An alternative is to have your wife offer them Japanese baked goods... but you can only do this if you have a Japanese wife like me, (and of course she better be a good cook!).
