The Frank Covey framework also makes you think where you are spending your time, and I like it’s simple approach, that is not a set of fixed rules but instead some guidelines that you need to apply to your situation. I describe how I am thinking in using it in another thread, that has already been mentioned in one of the above posts.
Quote from my other thread,:
I have never tried it, and I only came across it this week on Twitter, and someone mentioned the minimalist bullet journal in one of the comments, but I don’t remember the tweet. So this seems to be a simpler version of what you found 
A Google search will return plenty of results for the minimalist bullet journal.
