Too many times people try to make their life peaceful by controlling other people and their environment. This will fail every time. The best way to find Shalom is to work on ourselves. If we can learn to love even our enemies there is a good chance that nothing can offend us. Messiah told us to cleanse the inside of the vessel and the whole thing will be clean. If we are annoyed easily my little things we have a lot of work to do on ourselves. We can't point the finger at other people claiming they made us angry. Our anger is our own. We see this reflected in Messiah's example when he was crucified on the tree. All that they did to him never made him angry. He is our perfect example.
