Making more income requires a significant amount of time, stress, and energy which would come at the expense of my family.I've also gotten to the point where it's harder to delay gratification--it's not a skill my wife is great at (so delaying gratification frequently means I go without, and she doesn't) and spending $2000 to go see nephews and nieces is much more important than having an extra 5 shares of google or MSFT. 

.$74.00 Emerson Sensi WiFi smart thermostat - https://www.amazon.com/Emerson-Thermostat-Version-Energy-Cer...This is the exact one we have in our lake house.

Then you have the energy efficiency of the home, its size etc.

I don't think that will be that fast, because we need to solve the energy problem first.

Obviously we don't even open a link if it has less that 4 stars (honestly 4.5) and from there we read over all of the reviews!

What a waste of energy. 

The ones showing 5 stars all look and sound the same, I'm sure they were paid for that. 

There is a 5 Star Resort there, golf course, beach, and some tasty restaurants.

Time, Interest, and Energy. 

We did have a set of guests who left dents in the drywall, blood and vomit on the sheets and towels, gave zero heads-up, then got upset they got a 1-star rating instead of the 5 they're used to.
