Definitely my parents.

From them I received all the values and principles that guide my life today. What was their secret? Living the best life possible, despite their virtues and flaws like any other person. My parents lived a moral, dignified, honest life. They showed love and respect for oneself, for others, and for nature. Their example is the foundation upon which my siblings and I also try to build our own lives. In the same way, the example we received is the one we now pass on to our children.

The best way to be a parent is by example.
