1. Stop trying to reason with unreasonable people....unless they are buying the drinks.
2. Anything that Aristotle ever suggested (from 2,000 years ago).....bank on it, and live your life by his 'code'.
3. If someone seems mentally deranged....keep a good six foot distance.
4. If people appear in a cult-like state of mind.....then they aren't sane enough to sit on your porch and sip your tea or whisky. Send them home.
5. If you reach a point where you think censorship is a good thing.....you might want to find some Jesus-like person to trust.
6. If someone comes up to you with a problem, but their statement adds a extra-layer....suggesting they don't want to really fix the problem (they just want to retain/hold it)....maybe you should change the topic of discussion to favorite Beatles tunes, the strategy of poker, or best episodes of Star Trek.
7. Maintain a balance on 'free' stuff.....other than a handshake, a wink, or a bit of advice....nothing is really free.
8. In a normal day, you will likely bump into 200 'experts'. You might want to evaluate things and regard 90-percent as marginal experts, or fake experts.
9. You need to get used to 'failing-up'. It means people hired up a marginally educated or capable person.....knowing they were ill-qualified for the job, but the system requires management to hire such people. Fail-uppers will eventually reach CEO status, and even become President of the United States (this may have already happened).
10. You don't always need a plan, but in 99-percent of cases....it helps to have 'something'.
