Being organized is not just something to make you seem professional, and not something that should be a big chore to do.
Organization makes your life move more smoothly and efficiently. This in turn leads to a lower amount of stress.
I am not talking about alphabetizing your books, or sorting your socks by color. Though going to that extreme can simplify things greatly, I am quite sure it would drive most of us crazy.
I am talking about things as simple as keeping your desk in order, and keeping clutter from gathering. There are many great ideas out there for easy organization methods.
The easiest is to find a place for things when you are done using them, even if there was not a good place before. This is something that takes getting used to, as we all want to be a little lazy and just throw it in the nearest convenient location.
I am quite sure that we all have that box of cords in our home. The one with all the power plugs and cables from every device we have ever owned. We keep them because we feel we may use them again some day, but when we need one the whole thing is a big mess of tangled wires. This is a key example of this problem. If we took the time to secure the cables before they went in the box we would not have this problem. Yet we don't want to go fix it now.
My problem was always how do I secure the wires. Tape leaves a sticky mess, cable ties are very inconvenient and hard to work with, rubber bands get brittle and snap. I found on Amazon the perfect solution, velcro cable ties. Re-usable, convenient, economical, and pretty easy to use.
The next problem I had was my desk. All the mail, and all sorts of manuals and papers seem to always appear there. It ends up a mess, and I just toss it all in a heap to the side. This one was an even easier solution, stacking letter trays. Though not a perfect solution, it allows items to be sorted as they are put on my desk. It at least makes it easy to sort out what is important and recycle what isn't.
There are many more simple economical things you can get to help with organization that are not only easy to use, but will actually make it more of a habit than a chore to keep organized. It is all about finding the right solution for the problem rather than letting the problem get away from you.
