I believe that when it comes to particular techniques and tips on working on middos-everyone finds something else that works for them.
Personally, when it comes to anger, the best thing that works for me was programming my mind to realize that every disappointment/aggravation comes from Hashem. Once this is REAL in your mind, but seriously real, anger management is much easier. Try getting angry then. It’s much harder.
Hatzlacha!
