Sometimes, turning something on its head (such as Time Management) can create new ideas and ways of looking at it, and how it applies to your working life. The truth is, there's only ever going to be 24 hours in a day, so better time management should mean more time. But it's what you do with that time that counts. In order to remain healthy - both physically and mentally - at work, you need to reserve time for some things that shouldn't be managed, squeezed or messed with.

Sleep time

If you stay up all night (or even just until a late hour) to finish a deadline, then yes, you might make that deadline, but you're causing more damage in the long term. You'll arrive at work the next day far less productive, bleary eyed and yawning.

Science proves that sleep makes us more productive by improving concentration and resetting our mental buttons - so forget the all-nighter, and ask for a 24 hour deadline extension instead so you can pace yourself. There are very few projects that have such strict deadlines that you should eat into your sleeping time.

Social time

Family and friends are important in our lives, and if you neglect them in favour of work, it's detrimental to them as well as you. Always set time aside daily for time with your family (how many husbands and wives complain their partner is married to their job? It happens all the time - don't let it happen to you). If you have children, enjoy them growing up because you'll see less and less of them when they get older, and you'll wish you'd have spent the time.

That's not to say that you should do this during work time, but get into a routine where you can manage your work/life balance better. Don't forget social contact with your friends, either. Even if you work with them, try and keep work off the agenda and focus on the fun things that your friendship is built around in the first place.

You time

Many of us are so busy pleasing other people that we forget that everyone needs time and space to themselves. It's very rare for some of the busiest of us, so enjoy it while you can. Whether it's taking the phone off the hook whilst indulging in a long hot bubble bath, or even something more active such as going to the gym or browsing a bookstore, make sure that you don't neglect your own time - again, it's scientifically proven to be better for your overall health and well-being.

Finally, don't forget that work time itself needn't be all stress and bustle. Have a chat to a colleague, take one lunch break a week out of the office and get some fresh air. Exercise at your desk, help mentor someone else in the office, or volunteer for the corporate charity - these are all things that can mean time is well spend instead of us trying to squeeze every minute out of every day. You - and your mind and body - will be glad that you did.
