In any role, there are three sources of motivation.
First is what the company you work for values. This is not about the principles you read on the website, but what happens at the company at certain critical times. Is it an environment where people generally care about each other? Is there a lot of control, processes, red tape? What happens when somebody disagrees or fails? Who gets promoted?
Second is the relationships you have. Both with your peers and with your managers. When the first source fails, this becomes incredibly powerful. How often do you hear from them? Do you know them on a personal level? Do you have supporting people around you, and do you have people you feel like giving your support to? What happens when somebody leaves?
Third is the work you do. When the first two fail, this is all you have left. How do you feel about the tasks you are being assigned? Are you proud of what you do? Are you learning something new? Would you do this somewhere else? Can you?
The most important question: where do you get your motivation from right now?
