There are many things you can do, such as reading, traveling on weekends, yoga after work, swimming, badminton, watching movies, or taking classes, learning languages, cooking, baking, or going to the gym. It depends on how you want to play. It's normal to encounter unhappy things at work. According to your idea, you can ignore it and correct your mistake. You can also vent through sports, singing and bars. You can still cry! You can make an appointment with your friends to talk about those unpleasant things. Carnegie's book is very good and can teach you how to be a person that everyone likes. Life is very tired, but it can also be very pleasant. Come on! :)
