A god way to measure what to keep is ask yourself, when was the last time that I used/ wore / enjoyed this item? If the answer is longer than 12 months, then it’s time to get rid of it!
If you have several sentimental items, then neatly display them on a shelf so you can actually enjoy them.
Less is more, and by getting rid of clutter, the more important things reveal themselves.
