Good first step
Start with clothing or shoes. Both are easy to judge visually and easier to cut down fast.
Starting out
If you are new, the best move is usually to make the whole process smaller.
Most beginners get lost for the same reason: they save too much before they know what they are even trying to compare. Start with one category, one goal, and a short list you can still remember.
Easy mistake
Do not mix shoes, bags, clothes, and electronics into one giant list on day one.
What to do next
Once one lane feels clear, move into that category and stop adding random extras.
