Not getting enough sleep

If you’re always sleep deprived, chances are you’re not getting a lot done at work. Some people choose to deal with this by consuming lots of caffeinated drinks, but there’s just no substitute for a good night’s sleep to be able to function well at work. Aim to get at least eight hours of sleep daily to wake up fresh and energized, ready to take on your day.

Not eating well or not eating at all

You may think that you’re boosting your productivity by skipping meals, but this can have a bad effect on your health and work performance. Your body needs food as it fuels your body throughout the day, and you need to consume the right kinds of food to keep you well-nourished.

You use poorly-made tools and gadgets

That pen that always leaves a huge blot on your planner. The stapler that needs to be whacked repeatedly before it works properly. Your computer that takes too long to boot up. Believe it or not, poorly-made tools can affect your productivity, and it also causes a lot of frustration in the long run. So get yourself a nice pen and a stapler that actually works, and see what you can do with your PC to improve its performance.

Your desk is a mess

You may say that your messy desk is just organized chaos, but in the end, clutter is clutter. A messy or disorganized workspace gives the impression that you’re not in control, and your performance also coincides with your space. When your desk is organized, you have the motivation to work. So make it a habit to clean your workspace daily and pare down the items on top of your desk to the essentials.
