Delegate Tasks — One of the easiest ways to reduce stress and be happier at work is to delegate some of your smaller tasks to others when possible. Make a list of your tasks and decide what you need to tackle personally and what you can delegate to others. With fewer things to worry about you’ll be able to better concentrate on the important aspects of your job.

   Make Friends at Work — It may be conventional wisdom that work and personal life should be kept separate, but most people find that having close friends at work makes going to work more fun. If work stress is getting to you, or you simply want company for a coffee break, a work friend can be a great way to make your work environment, and you a lot happier.

   Personalize Your Workspace — You’ll be a lot happier to spend hours at your desk if it’s a pleasant place to be. Put up some pictures of friends and family or get some nice desk accessories to spruce up your space. But be aware of office rules and politics and stay tuned with your overall office environment.

   Find a Job You Love —While this may be easier said than done, having a job you enjoy can make a big difference in your overall happiness. You spend a good portion of your waking hours going to work, so shouldn’t it be something you enjoy? Think about what you don’t like and do like about your current job and what you’d truly like to do. It may take some work to make it happen, but it will be worth it in the long run.

  Get Outside —A little fresh air can make a big difference. Take some time out of your workday to get away from your desk and go outside.

   Sit Up Straight —Sometimes the key to feeling more energetic and productive is to act the part. Stop slouching in your chair and sit up straight. Not only will it help your posture (not to mention reduce back and neck stress) but it will also help you feel more alert.

  Keep Your Desk Clean —A chaotic desk can make completing even the simplest tasks an ordeal. Take a few minutes each day to tidy up papers on your desk. It will help you work more efficiently and reduce the amount of time you spend looking for those important documents.

   Don’t Procrastinate —If you have a nagging task that needs to get done, don’t put it off. Get the least desirable of your responsibilities out of the way as soon as you can while you feel energetic. You’ll feel a lot better after it’s taken care of, and you’ll be able to focus your attention on other tasks without the worry in the back of your mind.

   Clean Out Your E-mail — Don’t let your inbox overflow with e-mails. Create a simple filing system for e-mails that you need to keep, and periodically move the rest to the trash can. This will make it easier to find what you need, and also help your e-mail function more quickly.

   Learn to Say No — Saying no can be a difficult thing to do. It can make you feel guilty or that you aren’t meeting the expectations of others. But sometimes, in order to maintain sanity, no is the only answer. If you’re too busy or already have other commitments just say no- you don’t have to please everyone and you’ll save yourself a lot of stress and worry.

   Make Things Manageable — Sometimes a big project can seem so daunting you hardly know where to begin. If you break it up into smaller parts it can become more manageable, and you’ll be happier feeling like you are making some progress by checking off each of the smaller parts as you complete them.

   Take Vacations —Many people think they simply can’t take a vacation, that their work won’t be able to get by without them and convince themselves that they can’t get away. But taking vacations is part of being a healthy and productive employee. Without breaks from work, you can become burnt out and your work might suffer as a result. So use your vacation time wisely, even if you just spend it at home with kids.

   Schedule Around Energy Levels — If you always experience a post-lunch slump in energy then don’t schedule an important meeting or your most difficult tasks for that time. Work with your body’s natural energy highs and lows as much as possible. It will make you more productive and reduce the amount of stress you feel at work.

   Ask for What You Want — Think you deserve a raise? Want to work from home a few days a week? Then don’t be afraid to ask. Many people fear the rejection of their requests so much they never bother to ask. It’s true, you might not always get what you want, but it’s better to know where you stand than to waste your time wondering.

   Always Be on Time —Some people truly struggle with being on time. The fact is, being late makes you look unprofessional. If you have trouble getting out the door on time in the morning, get up a few minutes earlier or lay out your clothes and work necessities the night before. Not always having to rush will not only make you look better at work, but it will also reduce the amount of stress on you.

   Don’t Hide Behind E-mail — E-mail is a great tool for work but there are some things that are simply better discussed in person. Make the effort to go into a coworker or boss’ office to discuss things in person.

   Protect Your Private Time — It can be hard to balance work and personal time. But in order to be a happy and healthy person you need time to yourself outside of work. Schedule times when you will be completely work free - no e-mail, cell phone or PDA and do something you truly enjoy doing.

   Ask for Help — Sometimes we simply have more than we can handle. There is no shame in asking for help if you truly need it. Let your boss or coworkers know that you’re in need of help and see if something can be worked out to lighten your load.

   Control Interruptions —While we all love getting the occasional forwarded e-mail or coworker that stops by to chat, these kind of interruptions can make it very hard to get work done. You cannot eliminate interruptions, but you should do your best to control them. Set aside blocks of time where you don’t check e-mail and let calls go to voicemail so that you can complete the work you need to with fewer interruptions.

   Work Close to Home —Working nearer to home can eliminate hours spent commuting. Commuting is essentially time wasted and you’ll be happier putting your energy into something more rewarding.
