I'm not a parent, but I've learnt the value of this lesson the hard way after seeking validation from my father for many years of my life. The first (and only) time he was ever able to write me me a letter telling me he loved me has stayed with me for life. The words strengthened me. They helped me believe in myself. And I've kept that letter to this day.
As I've declared February the month of love I want to encourage you not only to tell your kids, family and friends that you love them, but tell them why. Don't just stop there. Take a moment to tell those you work with that you appreciate them, and why. We all need a bit of encouragement, so why not take the opportunity today to encourage someone in your world.
