I came up with this "motto" about half way through my mission one day, the words just popped into my head. I think it helped me become a better missionary.
When you live life with this thought in mind I think you do a little more to be a little better because we don't know when our last opportunity will be to make an impact.
I forget my motto occasionally but I remember it better when I'm on a roadtrip and see something I want to take a picture of and remember.
Sometimes I think, oh we don't have time to stop or, it'll be inconvenient to turn around but when I shove these thoughts out of my mind, I'm so glad I do because I get some of the best photos or memories.
It's not always a photo but it's doing something that when you have a tiny thought of something you want to do and instead of dismissing it, you act on it, it creates some of life's best opportunities.
What have you done lately to 'leave no regrets' ?
