12 Rules to Live By - Robert Louis Stevenson
Make up your mind to be happy. Learn to find pleasure in simple things.
Make the best of circumstances. No one has everything and everyone has something of sorrow.
Don’t take yourself too seriously.
Don’t let criticism worry you. You can’t please everybody.
Don’t let your neighbors set your standards; be yourself.
Do things you enjoy doing but stay out of debt.
Don’t borrow trouble. Imaginary things are harder to bear than actual ones.
Since hate poisons the soul, do not cherish enmities and grudges. Avoid people who make you unhappy.
Have many interests. If you can’t travel, read about places.
Don’t hold post-mortems or spend time brooding over sorrows and mistakes.
Do what you can for those less fortunate than yourself.
Keep busy at something. A very busy person never has time to be unhappy.
A more generic version:
If you open it, close it.
If you turn it on, turn it off.
If you unlock it, lock it.
If you break it, repair it.
If you can’t fix it, call someone who can.
If you borrow it, return it.
If you use it, take care of it.
If you make a mess, clean it up.
If you move it, put it back.
If it belongs to someone else, and you want to use it, get permission.
If you don’t know how to operate it, leave it alone.
If it doesn’t concern you, mind your own business.
I am going to have to think of my own set of 12 principles and post them later ... what are some of yours?
