Be kind it costs nothing

Use critical thinking skills

Love and care for your family and friends

Develop self-love

Don't lie, cheat, steal, etc.

Focus on one (or more) careers and develop them

Have a solid work ethic

Ego, conceit, vanity, and arrogance are dangerous things

Be careful with pretense, assumption

Think before speaking and acting

There's more but that's a good start. No god required.
