It happens occasionally, this feeling. It's usually during times of great change, when life is moving much too quickly. Perhaps it's a way of gaining some control. It can be an internal and external clearing out and restocking. Reconsidering what's important and what's not. Wondering how some things ever were so important. It's a fine feeling that discarding, throwing out feeling. Getting rid of papers from long ago. Deciding what should be so highly valued that it maintains a place in one's future takes some time and effort. You have to be ready to make those decisions. Decisions about letting go of those things no longer useful, no longer relevant.
Social media serves as a good reminder about how quickly things can come in and out of favor. It could even provide a new model for living, reminding us that many things are so important for such a short time, often just until the next important thing comes along. It can be hard to keep up, so a regular renewal process fits into this model. It fits the pace of life and it certainly fits with the throwing away culture that we are developing. There is certainly nothing like getting rid of those unworn, or very well worn, clothes, shoes and handbags that clogged the cupboards of the home. It takes decisive action and an ability to detach from the memories they hold. You need to detach to let things go and you need to detach in order to reattach. That's why this time of renewal is so crucial.
