Numbers 2 & 3 are very good advice.
Number 1 is nonsense. There is no unseen judge balancing the scales. Do good because that is the sort of world you prefer to live in. Don't expect rewards or retribution.
First of all there are 12 laws, not 3. Secondly I think you are missing the point entirely of rule 1. Rule 1 is like the "Golden Rule" and has nothing to do with retribution but rather just doing good for the positive feedback loop. As an atheist, I don't expect any reward but doing good is beneficial for everyone.
Here are the other rules
6. The Law of Connection
7. The Law of Focus
8. The Law of Giving and Hospitality
9. The Law of Here and Now
10. The Law of Change
11. The Law of Patience and Reward
12. The Law of Significance and Inspiration
