Munger, if you want to achieve success and live a good life.
During a speech at the University of California in 2008, he gave the following advice,
1. You must ensure that you spend less in your lifetime than you earn.
2. Maintain the ability to learn throughout your life.
3. Collect the mistakes made by others and then avoid them.
And so on... your life will be good.
Do not expect any book, any principle, or anything to solve all problems at once.
