Make sure everything has its place... and label, if need be
Get rid of papers. They end up forgotten and you don't need most of them... Almost everything is digital these days
Don't pile things, store vertically so that you can see everything on opening a drawer or cupboard
Only keep items that bring you joy. Ask of everything 'does this bring my joy?'
Keep small change in your wallet, not discarded and useless in pots around your home
Plastic bags. Get rid, or fold and store upright in a rigid container to prevent over accumulation
There! Doesn't that feel better!!
