I happened across another list by a humanist
1. Love well
2. Seek the good in all things
3. Harm no others
4. Think for yourself
5. Take responsibility
6. Respect nature
7. Do your utmost
8. Be informed
9. Be kind
10. Be courageous
I think # 4 is very selfish. Why would you just think for yourself. It is better if you will also care for others.
I think you must replace it with this : Quoted bottom.
1. Though shalt not use force.
2. Though shalt not deceive.
3. Be excellent to one another.
It is not saying, "Think about yourself", but "Think for yourself"...
Do not rely on other people to think for you... have a critical mind... be skeptical and think about shit... don't believe everything you see/read/hear without first thinking about whether it is true or false
Also note, this isn't my list (though it looks eerily similar)... it came from a book:
