How can I stay motivated under work pressure?

1.Recognize that work pressure is work pressure - try not to bring it home,difficult as this is.

2. Get organized - take a serious look at how you work and what can be changed, delegated to someone else, done in a different way, or discarded altogether.

3. Work to your strengths - when are you more awake and motivated?  In the morning, in the afternoon or just before the end of the day?  Do the impotant work which requires your full attention at the key part of the day (hopefully before the end of the day) when you are feeling most energized and ready for action.  

4. Break the tasks down.  Make telephone calls asap.  Arrange meetings asap.  Keep those people who need to be informed of your progress (takes some pressure of your head and let's them know you have item in hand). Send short and simple emails.  Clear the email Inbox. Cut down on the number of emails you send.  Remember emails are largely interruptions.

5. Keep desk area as clear as possible and have only current task to be dealt with on you desk.  No work should be in drawers hidden away.  Only items infrequently used or already dealt with and kept for record keeping purposes need to be in drawers.

6. Start of the day - have a clear idea of what you need to achieve.  If any problems let people know, they may be able to help you well in advance of a deadline or it gives you an opportunity to really look at your workload.  Is the workloard realistically manageable?  Are the deadlines impossible to meet? Are you saying 'yes' to stuff when really you need to say 'no'?

7. End of day - about15 mins to half an hour before the end of the day, look at what has been achieved and what is outstanding.  Clear the desk, delete/filter/archive emails.  Prepare for the next day.  

8.  Leave work.  Work will always be their.  Enjoy your home life, exercise, socialize, do hobbies and develop interests anything unwork related.  WORK TO LIVE, NOT LIVE TO WORK.  

Take care.

Be self motivated.
focus on the positives that you have, work on the circle of influence, try to move things from the circle of concern to the circle of influence, otherwise ignore it.
