When you realise you need to get something done, you probably think to yourself, "I have to do that soon." But that type of thinking disrupts your motivation in two ways: by messing with your sense of time and robbing you of urgency.

As we have argued in the past, email is not the problem - we are. And it's not just the productivity drain or the antisocial effects of constantly checking our phones and computers for new messages.

A day may be 24 hours long, but you have to sleep. That leaves you with less time you can actually use each day - about 100 10-minute blocks. This simple exercise can help you determine if you're spending them wisely.
