Think First: When you are getting organized you need to do it not just have to have something look good, but for a "higher purpose". Eliminate clutter--eliminate stress! Have an end goal. Determine what are the best benefits of getting something in particular organized.
Have an Organization Plan: Before you start, plan what you want to do and where you want things to go. Map it all out. That way you won't get in the middle of sorting things and not know where to put the things you want to keep. This would be a good time to ask your family what they lose all the time, or some ideas on what would help them stay organized too.
Smallest to Largest: Start in the smallest area first. Your purse, the room you are in all the time, bathroom drawer or fridge. Small tasks that can be done easily gives a sense of accomplishment and will drive you to continue to organize. By the time you get to a big job, you will have organizing down and the bigger space may not take as long as you thought it would!
Avoid Distractions: Organizing is a bit different than just spring cleaning. It takes careful thought, prep and focus. Having distracting music, the TV or being on your phone while you do the job will just cause delays and distractions. Keep the dancing music for when you are dusting or straightening!
See the Change: Organize something you (and everyone else) will see first. It will get you inspired to continue and remind you of a job well done.
Keep it Up: Always put things up so you don't have to deal with it later. Label boxes and containers so you remember what goes in where. A little extra time putting up as you go will save more organizing time in the future!
