I'd been working on eliminating that habit, with little success, until I thought of utilizing Ho'oponopono.
Ho'oponopono is an ancient Hawaiian practice of reconciliation and forgiveness. It involves saying four phrases: I love you... I'm sorry... please forgive me... thank you. I've used these phrases for many years to help me maintain balance and see things from a higher perspective.
The other day was the first time I used the phrases while driving. I am happy to say that while running errands and driving to several locations, even while witnessing someone run a red light, and another person nearly cause a collision by crossing four lanes of traffic, I didn't swear. Not once.
Ho'oponopono is going to become a vital part of my driving experience. So, if you see me o the road and it looks like I'm talking to myself you'll know I'll be saying: I love you... I'm sorry... please forgive me... thank you.
