There is a great website I have been spending time on recently. It's the 2SecondLean website. The developer of the website owned and runs a business in the Northwestern US and from the looks of this site he has a successful business. I am going to share a video about a lean adjustment he made to his plane and this is the epitome of what I see with lean. It's simple, quick, and effective.
There are some buttons on the dash of his plane and if they are not set properly after landing the plane they can drain the power off of the battery. Take a few minutes to watch this video and then ask yourself "what is bugging me at home or at work"? Often small improvements can make a big difference over time.
