Getting stir-crazy and bored by the incessant monotony of work can be killer to creativity, and even happiness.  Work becomes the activity you tolerate to pay the bills, and no one should feel trapped by the almighty-monthly-bill.  This isn't to say you hate, dislike or want to change jobs, just that you could use a little more pizzazz around the office to put the pep back in your step as you go to work each day.  Here are a few helpful tips on how to reinvigorate and reenergize your workspace.

Decorations

Your workspace should be filled with pieces of art that you really enjoy, and photos of loved ones to keep you company.  Keeping your space occupied with visual stimulation that you find appealing can make the daily 8 hours much more pleasant.  Also, switch up the art and photos from time to time, either with ones from home or new ones to keep things fresh.

Feng Shui

The way you orient the furniture in your office also makes a big difference.  One great way to get the creative juices flowing again, is to try moving your furniture around, or even just take the visitor's chair on the other side of your desk for a change.  By simply changing your position in the room, you can gain a whole new perspective, and chances are you'll find a whole new mindset.  If rearranging your furniture isn't a viable option, maybe consider how open or unused space in the room could be used.  Maybe add a couch?  A plant?  Life-size cutout of your favorite actor?  (Just kidding.)

Letting the ideas flow

People often undervalue their ideas, mostly because they're too hypercritical of themselves to recognize a brilliant idea in a simpler one upon first thought.  Instead of picking through your brain for the most intelligent, bright ideas you have, write every single idea down as it comes to you, and then start wading through until you find what you're looking for.  Don't underestimate yourself; your brilliance shouldn't be stifled by nay saying.

Vary your routine

Part of the monotony of the daily grind is the routine we set ourselves in.  It can be costly to our creativity and happiness to stick with what we know every single day, over and over again.  Eat lunch at a different place, with a different group of people.  Change seats at meetings—you haven't had an assigned seat since high school (middle school?), so grab a different seat next time around.

New office accessories

This one may seem like a no-brainer, but even just buying some fun pens or a whiteboard and dry-erase markers can make work feel more inviting.  Have some fun in your workday, even if it's as simple as writing in purple instead of black.  You'll love the difference and sense of fun it gives.
