This has saved me so much over time when it comes to pens and if you teach people this, they won't have the need to steal your pens anymore!
For anyone who does a lot of computer work, this one is a must. TenClips (Windows only, there seem to be plenty of similar applications though) will hold up to 10 things in a clipboard simultaneously. Simply press ctrl +1, ctrl +2 etc. to assign the different items you want to copy. I end up using it everyday for various tasks. Needing to copy/paste different sections from an article or document and not wanting to flip back and forth between the pages. Needing to save an address, name, or snippet of info for later? Just assign it to "2" and then you can continue as normal and still copy/paste other things in the meanwhile.
This is an easy tip that everyone most likely has the supplies to accomplish. If you shatter glass on a hard floor take a piece of sliced sandwich bread (Wonderbread etc) and after you pick up all of the large chunks of glass press the piece of bread down on the floor in the general area. The bread easily picks up all of those little invisible shards!

It's easy to delete newsletters and ad emails because it's much faster at the time than going to the trouble to unsubscribe. Instead label junk emails 'unsubscribe' and archive them. Then, once a week take 15 min to unsubscribe to all emails labeled for that week. You will reduce your email management time significantly following this practice.
Them: "I'll take care of this." You: "Oh, that's very generous of you, thank you. How about I cover the tip?"Taking this approach allows you to avoid the awkward "No, I insist" back-and-forth. It takes a little of the expense off the payer but still allows them to make a generous gesture.
When painting for multiple days, you can put your wet paint brushes in ziplc bags and place them in the fridge overnight. At those cool temperatures the paint will never dry. Take them out the next day, let them warm up to room temp, and you're ready to paint. This same thing can be done between coats if it's taking a bit long for each to dry.
Start 2015 off with an empty jar and fill it with notes of good things that happen. On new years eve, empty it and see what awesome stuff happened that year.
