Everyone these days seems to have taken to the Konmari method of tidying up. While this way of organizing is completely effective, the oldest folding hack in the book still stands up when you only have three seconds to fold a shirt. Besides, it's kind of makes folding fun too.
It looks a bit tricky when you watch a video quickly but once you figure it out, it's a total breeze. Lay a shirt flat and follow the images below to fold a t-shirt like a pro.

Make sure you position your right hand near the top by the collar. This will be where your side fold is created. Then cross your right hand over your left to pick up the bottom of the t-shirt.

Pull your left hand through to the bottom of the shirt and shake it out. Fold the shirt over to complete the fold. Voila, t-shirt folded in 3 seconds. It takes a few times to get it perfect but if you can nail this hack it's a fun trick to share.
