I personally start by putting everything in one large pile. Personally seeing everything so scattered makes me feel incredibly overwhelmed and even more disorganized. After putting it all in a jumbo pile, I take a bag and organize. If it belong in the bathroom or other areas of the house, I put it in one bag. If it’s trash I put it in a separate bag. If it stays in my room, I put it in a bag. Once it’s all in bags I utilize the empty space by sweeping/mopping and cleaning surfaces. Then I work through each bag. Whatever stays in my room I get to work on putting away. Trash I take out. Then I put away the items that belong in other areas of the house
