I believe that my actions show my beliefs, not my words.
I wrote a letter to my kids a few years ago. It's three pages long, and it sums up my life experience of four decades. By the time they reach adulthood, they will have heard most of their father's advice in that letter: live in the moment, do not attach yourself to physical things, treat others the way you would like to be treated, etc. I sealed the letter in a white envelope, and wrote instructions that nobody should open it unless something horrible happened to me.
As a police officer, I have seen life disappear in an instant. I realize that could happen to me at any time. Yet knowing that letter is there in my locker makes me more comfortable with my own death.
Every day, when I open my locker, I see the letter. It makes me aware that I should be careful at work, and show my children and the people I have connection with that I try to practice everything I have written. If that day comes and my children finally read the letter, I hope that because of my actions, they will take my written beliefs to heart and improve upon my example.
But for me, it's not enough to write down my beliefs. I try to be the best person I can be every day—even in very difficult circumstances. I am more successful some days than others, but sometimes I curse too much. Sometimes I am cynical, unwilling to believe that people have good and honest reasons for doing something. I also get stressed and upset, yelling at my kids sometimes, and sometimes I am not as loving or as sympathetic as I should be. In fact, I am far from perfect, but I hope my children will eventually realize that perfection is an illusion. What really matters is that, instead of just writing down our beliefs, we all take action to be the best humans we can be.
