Since we have no dog in the fight sometimes the observation is more detached.  

I dance a lot, too.I also do what you listed in #3 Savers (though I have a different but similar term for it).Whenever I feel like I've hit a wall or feel tired, I get out of my routine & take long walks around the neighborhood or park & casually observe nature.

Observe others and don't make the discussion all about you. 

Quick story, I was watching Live PD last night and they observed a woman hand a bag to a guy at 1am in a high drug area.  

Go to the court house steps or other arena where houses are up for auction, and observe the big guys and gals who are actively buying properties to flip (be prepared for a cold reception - just watch how they do what they do); my husband and I did that and decided that wasn't the way we wanted to buy properties, but did learn something in the process.Join a local REIA and get involved, volunteer to help out in the organization and/or with another member of the group with their properties and projects.

That's a great observation Max.

Going to the neighborhood/city/county to observe and talk with people will provide the information needed to make good decisions.  

I have grown up in the area for the past 20 years, so I'm happy to share thoughts on next up-and-coming areas and what I've observed as market driving forces in the areas surrounding the city.

However, we can observe that renovated homes may sell faster, which can this render a time adjustment - but time adjustments are tricky requiring lengthy explanations in the addenda.
