I posted in the ‘Introduction” section a few days ago and have since been reading and searching the posts here on DV.

Here’s my technique:
There’s a forest near my house which I’ve hiked 3 times a week for 20 years. When I’m going to sleep I ‘walk’ or ‘fly’ this route and look for anomalies.
When I see something different or out-of-place on the trail, I go to that place and look for things or people. I look for the answers to questions, and I readily find them.
