Forget hard work and perseverance. Getting ahead is as simple as tidying your desk.

According to a leading expert, having a cluttered environment reflects a cluttered mind, but the act of tidying up can help you be more successful. The advice comes from Jayne Morris, the resident"life coach" for NHS Online, who said it is no good just moving the mess around. In order to clear the mind, unwanted items must be thrown away to free your "inner world", she said.

Ms Morris, who claims to have coached celebrities to major business figures, said:“Clearing clutter from your desk has the power to transform your business. " How? Because clutter in your outer environment is the physical sign of all the clutter going on inside of you. " Clearing clutter has a chain effect across your entire life, including your work. Having an untidy desk covered in clutter could be stopping you achieving the business success you want. " She is sure cleaning up will be helpful even though some of history's biggest achievers lived and worked in messy conditions.

Churchill was considered untidy from a boy throughout his life, from his office to his artist's studio,and the lab where Alexander Fleming discovered penicillin was famously untidy.

Among the recommendations is that simply tidying a desk at work and an overflowing filing cabinet(陈列柜) will instantly have a positive impact on "your inner world. " Anything that is no longer used should not be put into storage but thrown away completely.

Keeping something in the loft, garage or other part of the house, does not help because it is still connected to the person "by tiny energetic li.nes", Ms Morris. claims.

She said, "The things in your life that are useful to you, that add value to your life, that serve a current purpose are charged with positive energy that refreshes you and enriches your life. But the things that you don't ever use and don't need anymore have the opposite effect on your energy.

Things that no longer fit or serve you, use up your energy. "
