Improving your workspace by keeping the surface clean can help you be more productive. Stepping away from the computer during the day roughly every half hour can also help you be more productive because it prevents eyestrain. If you're bored with your daily activities ask for something else to do. If you hear of an interesting project ask to be on the team and if you do not have the skills required for the project start developing them. Ask people to help you or take a class. The more skills you learn the more value you will provide the company.
