Direction 3: Dust has accumulated for so long, is this thing that was collected by you still useful to you now?
Tip: Re-examine this thing you collected at the beginning, think about why you collected it at that time, and after so long, is this thing still useful to you now?
1. If we find that a certain collection is no longer useful to us, we can consider deleting or cleaning it out in order to better organize our collection and leave valuable things.
2. On the other hand, if we revisit something in our collection and find that it is still useful to us**, then we should use it in time, or consider using it again at some point in the future**. This helps us make better use of our collections and meet our needs and interests more effectively.
