Whatever unfortunate issues you may have had with someone in the previous year, remind yourself it's better to let the issue go (I mean you can always forgive but you don't have to forget! ;) and to start the new year with positive energy. It sounds cliché but in fact many of the activities during Lao New Year, in many ways reinforce the ideas behind positive blessings, fun and togetherness.
And while we don't have new year's resolutions in Lao culture, one promise you can keep for yourself is to start the new year on a positive note. So say goodbye to the blahs of the previous year.
