Well, onward, here's how I make big decisions: like you, I research until I can't take in anymore. This makes for an "informed" answer. Then I sit back for a few days or weeks and check out my instincts again. If I have any reservations or sense any "red lights" I can trust myself to avoid a dubious situation.

It's easy to get lost in the details but I've learned to trust my sub-conscious to recognise patterns in the data. Also, the older I get, the more I trust this process. Maybe this wil help.....
