Dumb things people do that can mess up their lives

I'm taking this from the article linked below.   This is my adaptation of that article to real-life from geek.

1. Have a plan and be willing to overcome changes or problems.
2. Listen to the warning signs - things barely just happen without some sort of sign appearing first.  My brakes are squeaking should I:
• Ignore it?
• Turn the radio up?
• Make sure the brakes are in good running order?
3. Write it down.  When you change something important tell others and write it down.  Note:  Mom I took the car.  Is simpler than explaining to the officer, no really this is my parent's car.
4. If you have information beyond its' useful life - get rid of it.  Lawyers and IRS agents don't want to go through extra reams of paper they don't have to.
5. Apply updates in a timely manner.  Whether it is your car being recalled, furnace maintenance, computer software update, or a headache.
6. If it is a minor update let someone else be the guinea pig.  Wait.  Oh yes doctor, I want the latest botox treatment - not.
7. Keep secrets, secret.  Do you tell everyone your MasterCard number?  Nope.
8. Please everyone?  You can't other just want to argue.  Stand up for what you believe in.  Be Good, Honorable and True.
9. Please no one?  Just as bad a #8.  I know a few of these types.   Hmmm, the word jerk comes to mind.
10. Tell others, especially the important "others", how to do what you just did.  You never know when you won't be around to get something fixed or to get something done.  This goes with #3 above.

This is like the Internet hoax of 1997, Sunscreen Spill on the Misinformation Superhighway. Reference to Kurt Vonnegut's MIT Sunscreen speech hoax.
