Do you take your own advice?
It can be tough.
Difficult example: exercise every day.
Easy example: replace all your compact fluorescent (those spiral things) light bulbs with LEDs. Recycle (ha!) the CFLs.
I gave the easy advice to a young couple I know. It was accompanied with two boxes of LED bulbs. LEDs are getting very affordable. They’re even showing up at dollar stores. After gifting, one of the bulbs over the kitchen sink burned out. The pair of CFLs were installed in 2014. Both were replaced. Then I noticed a CFL in the attic. This advice is easy to take.
