1. Don't Multi-Task--So many of us are convinced that multi-tasking is a path to better productivity. Unfortunately, the opposite is true. People who swear by multi-tasking actually tend to get less done and produce lower quality work than those who focus on one goal or task at a time. The co-worker who brags about his or her ability to do "three things at once" is probably not doing any of them well.
2. Don't Forget to Take Breaks--Another thing that people tend to do is overwork themselves. The idea that being at your desk and refusing to make contact with the world for eight hours is wrong in more than a few ways. The effects of staring at your computer screen are bad. Taking a 15 second micro break from staring at your screen, generally once every ten minutes, can help reduce eye fatigue and general visual exhaustion by a huge chunk.
3. Don't Eat Lunch at Your Desk--Staying at your desk during lunch actually messes with your productivity, not only because you're exposing yourself to more eyestrain but also because you're forcing your brain to focus on the same topics and tasks for too long a period of time. Not taking a proper lunch break also tends to lead you towards unhealthy foods. Workers who are worried about getting back to their desk during their lunch hour tend to gravitate towards fast food or vending machines for lunch, which only offer empty calories and none of the energy workers need to make it to 5:00.
4. Do Similar Tasks at Similar Times—The brain tends to function by grouping similar things together, so it makes sense why it would benefit your productivity to do tasks that require similar skills, thought processes and actions at similar times. Planning out your day so that similar tasks can be completed within the same time frame can help you get more done by taking advantage of the way that your brain naturally works.
5. Know Your Socialization Limits--Another part of bad productivity at work is the tendency to socialize all day. It's nice to work with people that you get along with, but the urge to make work into an all-day social can have disastrous effects on your productivity. The easiest way to fight socialization is to set aside times when you can catch up on each other's day and the latest news, discuss any casual work issues or goings on and enjoy one another's company. It's easier to save a great story until the time arrives, rather than leave your desk in the middle of a project to talk to a co-worker for what could end up being a serious chunk of time. Set limits and stick to them.
6. Proper Use of Headphones is a Must—Headphones can really help you focus and drown out general office noises around you. When you need to escape a busy work space, headphones are great. A negative result of wearing headphones is that it can remove you from office culture. Tuning out all day can create a distance between you and your co-workers that can have a negative effect on communication levels and cause you to be a step behind when it comes to office knowledge.
