If don”t change how you do things then don’t ever expect new thing. If you can’t your habits, you shall keep on repeating the same things over and over again. Being an expert on a certain field, you need to have long-term experience. This means you can’t change the career field until you have some long peroid of the same thing. If you don’t want to be an expert in a certain field then keep changing careers to be an expert in changing. Thats how fun it is. But what stands is that you can never loose hope in living. Keep on moving. Days of changing times.
