Enough Already

Does anyone not own enough pens, coffee mugs or t-shirts? I'm drowning in mine.

To be fair, the excess t-shirts aren't really a problem.
Those that aren't particularly attractive? You can work out in them, or do dirty work around the house. Cheap? When they wear out, you can turn them into rags and drop cloths.
Embarrassing saying on the front? Give them to charity.

Pens and pencils are a little harder. If you're doing serious writing, you're not using a cheap ballpoint with the name of a mortgage company on it. But you probably do need a few writing implements around the house. The trick is to place them in strategic spots for those times that you actually need one. And then you'll lose and replace 90% of them before they actually run out of ink or wear down to a nub.
I have Pac-Man pencils. From 1982. They're not worn down. Heck, some of them haven't been sharpened yet.

Coffee mug surplus is tough to deal with. Mugs don't wear out or break often, so the attrition rate is low. Nope, they just grow one at a time, hopelessly alone, never to be displayed as a set. And as for the actual sets that you've gotten - they just get pushed further back into your cabinets. Their only hope of reappearing is if they have reindeer or snowflakes on them, and you can use them for six weeks at the end of the year.

Or, maybe you can sit one on that table over there, and use it to hold all these damn pens.
