Limitations can be liberating. It's a key reason why Twitter has been so successful as a social network. 140 characters and not one more. As a result, Twitter forces us to be concise with our messages and get to the point.
We can apply this same logic in other areas of our work to great benefit. By creating self-imposed limitations, we can increase our focus on what matters most.
Creating your daily to-do list serves as a good example. If you wrote down everything that you could do today, that list would be massive and long. But if you forced yourself to write down only 3 things. Things that you should do. You would be able to distinguish between what's most important and what's just on your mind.
So apply a self-imposed limitation to your work today. Try writing emails with no more than five sentences or scheduling no more than three meetings in a day. Discover how limitations can improve and enhance your focus.
