When faced with too much stuff, organizing becomes crucial to maintaining a manageable living space. Start by going through each item and evaluating its importance or usefulness in your life. Consider donating or selling items that you no longer need but are still in good condition. Categorize the remaining items into groups like clothing, books, electronics, etc., and find appropriate storage solutions for each category. This could involve using storage bins for out-of-season clothes or creating designated areas for specific types of possessions such as a bookshelf for books. It may be helpful to create a schedule for regular decluttering sessions to prevent accumulation of unnecessary belongings in the future.
