RICHMOND, Va. (BP) -- My years on the mission field were truly some the most fulfilling years of my life. They were joyful and life-giving. They were also tear-filled, stressful, and often just plain difficult. There were days I wanted to give up and move back to America. And yet, I'll never regret a single day that I and my family lived on mission overseas. I have learned a few things along the way. If I could go back 20 years and write a letter to my brand new missionary self, I'd highlight the truths that I needed to be reminded of every day.
