Bad things happen to everyone, including happy people. Instead of complaining about how things could have been or should have been, happy people reflect on everything they’re grateful for. Then they find the best solution available to the problem, tackle it, and move on. Nothing fuels unhappiness quite like pessimism.The problem with a pessimistic attitude, apart from the damage it does to your mood, is that it becomes a self-fulfilling prophecy: if you expect bad things, you’re more likely to experience negative events. Pessimistic thoughts are hard to shake off until you recognize how illogical they are. Force yourself to look at the facts, and you’ll see that things are not nearly as bad as they seem.
