There are certain verities (truths) that one should adhere to as we lead our lives. 

Not necessarily in the order of importance, some are:

1) There is no harm in asking 
2) Fun is more fun when you win
3) Luck is the residue of design
4) There is always a germ of truth in "just kidding"
5) You never get a second chance to make a good first impression 
6) Give a firm handshake as you stand and look a person in the eye
7) Live within your means
8) Respect your elders 
9) Listening is a super power
10) Never make the first offer in a negotiation 

You may not agree, but there are many more and I'm open to learning.
