There are already tons of resources to tell you about how to organize your stuff. To that tidy pile of wisdom, I will add the Bromeliad perspective - which is how to organize your closet in a way that is cheap and fun. If it's not cheap, we can't do it. If it's not fun, why bother?
My personal closet organizing breakthrough came after moving from a shared spacious walk-in closet to having my own closet that was about three feet wide. Surprisingly, I had a much easier time getting dressed every morning from the tiny closet than I ever did from the large one. All that I owned was visible and within reach. Any item that didn't pull its own weight had to be tossed - I couldn't spare the square inches.
The lesson I learned was that being happy with y0ur closet has little to do with the size of your closet or the amount of clothes you have. (Don't believe me? Have you ever noticed how the paparrazi always manage to catch some celebrity going to the supermarket without her stylist? And she's usually wearing something schleppy and awful like jogging pants and tennis shoes? Why is this? Because she stood in front of her giagantimous closet and could not find a thing to wear. )
So, here's my Monday tip to help anyone along the way to closet trimness:
Easy come, easy go. It's a lot easier to get rid of a $3 pair of shoes than a $30 pair of shoes. So buy cheap in the first place.
My closet organizing secret
I did a little inventory of my closet and discovered that everything in it was second hand with the exception of 12 items and one pair of shoes. The "new" stuff was all purchased on sale. A lot of the second-hand stuff was free.

As long as the global garment industry keeps pumping out billions of tops, slacks, skirts and shoes, you can afford to let go of that too tight pair of white capri pants. Let someone else have it.
You will find another pair eventually. Trust me. And it will be at least half off.
