I know some of these are old but I found quite a few very insightful for helping with things that are normally a challenge to do especially the key ring idea.. :)
Use a staple remover to save your fingernails when trying to add things to your key ring!
Put wooden spoon across boiling pot of water to keep from boiling over.
Use bread clips to save flip-flops with split holes.
Use sunglasses or a small convex mirror to avoid people sneaking up on you while wearing headphones at work
Use a post it note to catch drilling debris.
