How many times have you opened up your email, swearing that you were only looking for one message and as soon as you responded to it, you’d shut your email? And how often does that one email turn into twenty minutes of reading email and sorting through spam? I’ve noticed that when I have a boundary on my time — when the ringing of my timer reminds me that my time is up — I get back to the tasks that I really need to be working on. Your timer doesn’t even need to be fancy: you can pick up an egg timer at the grocery store (or borrow it from the kitchen), install a piece of software, use your microwave’s timer — you can even use a song as a timer, or an album if you need a longer setting. The key to a good timer is knowing when your time is up. Timers are useful devices. There are plenty of ways to use them to up your productivity and, if you’ve been looking for a way to up your productivity another notch, you might want to consider a timer.
