One place, either at home or at work, that should remain clutter-free, is your desk. This is your personal work area, so you need to know where everything is. You need to have organization, such as files and drawers for your important papers and holders for things like pencils, business cards and paper clips.
When it comes to keeping "your world" in order, that should also include your wallet. People place a lot of unnecessary stuff in their wallets that makes finding what you need almost impossible. Try using a smaller wallet to start with. Try keeping it free of garbage you accumulate. Also, go through it regularly to ensure that it remains clean.
Taking responsibility for your decisions and being truthful with yourself is such an important part in your quest to becoming a better person. After all, if you can't be honest with yourself, you will not be able to move forward successfully. You are in control of the person you were meant to be, so take control of your situation and you are one step closer to being that person.
