The best way to start a project is make an appointment with yourself.
Set some time for YOURSELF
Block off some time on your calendar and stick to it. Make it happen
On your organizing day, the next tough hurdle approaches: the first item to let go. The first piece of clothing, childhood memory or knick-knack from Aunt Betty is the toughest one to part with. After you get that first one "in the bag," the rest will be much easier.
Use your momentum to keep going.
Finish your appointment with yourself and schedule a follow-up to tackle the next area to be organized.
One of my favorite quotes:
-Yoda, Jedi Master
Reward yourself for completing your organizing projects as scheduled. Take a 2 minute longer shower, have a piece of cheesecake, buy a new shirt ... heck, have a beer in a martini glass.
Do something for YOURSELF that makes you feel
After all, you always wanted to be organized and look at the what you are doing now.
