Different decluttering approaches work for different people and situations.  By picking a system that works for you, maintaining it will be easier.  Here are some ideas.
 
Frequency of Use - Place your most used items in spots where they are easiest to access.  For example store foods used every day on eye-level shelves, store pens and paper within reach of your chair.
 
Color - Sometimes arranging things by color creates instant organization and retrieval.  Separate family storage by color, choose a different color pallet for the bed linens in each room, sort clothes in the closet by color for easy coordination.
 
Season - Group seasonal clothes, decorations, or equipment together.  Store in labeled containers in out-of-the-way areas until needed.  In some cases you can swap out the contents of the containers; summer clothes come out - winter clothes go in.
 
Order or Theme - Alphabetize DVD's, store books by genre, file taxes chronologically.  Choose any order that makes sense to you for sorting similar items.

 

So simple......you can do this!
