Standing up for what's right even when it's unpopular
Had a situation at work where the easy thing and the right thing were different. Everyone was going one direction and I went another. Took a hit for it but I sleep good at night knowing I did the right thing. My dad taught me that honor means more than convenience. Teaching the same to my kids.
Takes guts to go against the grain at work. Your kids will remember that kind of integrity way more than any paycheck.
