A lot.
Mostly:
A) Inner focus must be balanced with servitude, or a servant's heart. Serving others can heal even the deepest wounds.
B) Be kind. It's a hard life. Everyone needs kindness.
C) Don't try to be Superman, but rather do what you can to help when life presents opportunities.
D) Work hard. Hard work is it's own reward.
E) Model good behavior. Don't be a hypocrite.
F) World peace starts inside, and not by pointing fingers. If you can't change you, how can you expect others to change?
G) Be patient.
H) Learn to see the potential in others instead of their flaws.
I) Forgive the mistakes of others and move on. You can't live in true freedom if you are chained to events or actions from the past.
J) Don't hate your parents, or others for that matter, for making mistakes. This is part of the human journey.
K) Take marriage seriously.
L) Take parenting seriously.
M) Say I love you often to everyone you love.
N) Say "I am proud of you" when it is merited.
O) Beware of the Pharisees, or men who turn love into a set of laws.
That's all I have for now.
