Patience is one of the most important virtues in life. With patience you can do anything. Eventually you will make it on the path that you are meant to be on. This is where faith comes in. I hope that you can find it. When a person is ready to cut you off in traffic or someone is ready to be rude to you, it is better for you to remain calm and have patience for that person. No reason to let your stress level rise and put you in a bad mood. You can control over your emotions and others are not perfect. Sometimes, others are happy to see you upset, this is from their own wrong view and their unhappiness. Humans are flawed beings and we need to realize this with ourselves and with others.
