Aside from the basics, here are the nuggets of wisdom that are helping me the most in living my life more happily.
Embrace that you you are flawed and then learn when you screw-up. We are human and imperfect by nature and there is no way around this. I've taken to reflecting on each day and recognizing my triumphant moments and the moments I really train-wrecked. I then consider what some other alternatives to that train wreck may have been and how I could handle it better next time (because there WILL be a next time).
There is a blog post by DaringYoungMom titled, Drops of Awesome. Read it. Now. http://www.daringyoungmom.com/2012/12/19/drops-of-awesome/ She so perfectly sums up how important it is to recognize our daily efforts rather than dwell on all that we didn't do and all that we aren't. We aren't super people and I'm not quite sure when it entered our brains that we are supposed to be. Recognize what a waste of energy it is to ruminate on what a shmuck you are every time you handle something wrong (which happens often for everybody). Sometimes I yell at my kids, the house doesn't get cleaned, I didn't get dinner on the table, I forgot an appointment, I should have said no when I said yes, or I should have said yes when I said no, I killed my flowers because I forgot to water them, I spent money I really didn't have shopping at Black and White, I took a jab at my husband and the hundreds of other wrong or dumb things we do every damn day.
