Have a decluttered, clean desk in your office and at home.
You’ll be able to focus a lot better if piles of papers don’t distract your attention every few minutes.
Remove everything from your desk which you don?t need every day. Things to keep: post it notes, clean papers, pens or pencils in a holder.
My father had a master when he was learning as a technician. The master said he’ll close his eyes and someone can say the name of a tool. The master then easily went to the proper part of the workshop and removed the item from it’s place.
If you can’t keep your office or workplace organised, how do you expect that you can keep your thoughts organised and not wander when you need to focus?
So it’s highly recommended that you have a clean desk, and you have a way to organise everything into drawers, boxes and other places. If you always put something in the same place, you’ll never have a problem finding it. Trust me, this will save you a lot of time. I have a nice system on how I store my things, papers are organised into properly labeled folders.
