One Idea

Each day, unsubscribe to at least one unwanted email. It's easy to do these days (Gmail will do it for you, where possible, if you flag the email as spam). Of course, for a single unwanted email, it may be faster to delete it or ignore it, rather than unsubscribe, but in the long run unsubscribing will save time!

You can lose 25 lbs in 40 days on the "no ABCDE" diet (no Alcohol, no Breakfast, no Carbs, no Deviations, and no Exercise).

Do you get great ideas while driving? Make sure you don't forget them by creating an immediate and (semi) permanent record!

Often, I will have a few unrelated ideas/thoughts/questions that I need to keep in mind until I have chance to write them down (or otherwise save them, as by dictating them to my phone). A common and effective memory technique is to create an absurd image combining all of the ideas.

Both for work and personal purposes, I keep all related information in single (and long!) documents, which I call "mega" documents.

Storing tons of seldom-used items that you nonetheless can't bear to throw away is a great idea, especially if you do so with a simple-to-implement system that ensures you can easily find what you're looking for later!

Did you know you can use email to send texts?

When something is extremely useful and fairly cheap, I buy two or three (or more) of them, both to have a backup in case the item is lost or broken, and also to keep one in each place where I might use it (e.g., one at home, one at work).

Binder clips -- those black and silver clips found in nearly every office -- have many great uses apart from holding papers together.

When I'm at my work or home PC, I'm almost always wearing headphones.
