In my whole life, I have known no wise people who didn't read all the time - none, zero. - Charlie Munger
I've found having an attitude of life-long learning to be an excellent cure for boredom. Fortunately, our education only stops when we do. I hope to have the wisdom to take advantage of the lessons of my life and of those generous enough to share.
I've found Charlie Munger's concept of building a latticework of mental models to be a good guide. The world is too interesting not to learn what you can and tie it together.
To me, life-long education is about staying curious, pursuing that curiosity, and developing the skills to make those pursuits most fruitful. I recommend learning how to learn in case you're a bit rusty or interested in doing some quality assurance on your current learning process.
