For instance?
An example? My grandparent’s passed on a racist view of the world to my parents. This was an irrational thought pattern.
I am humble enough to recognize that I don’t have all the answers and that there’s a good chance that some of the ideas I am passing on to my son might be wrong. The best I can do for him is teach him to think critically, not to blindly accept everything he hears and to constantly re-evaluate what he thinks he already knows.
