Focus is one of the main elements to get anything done.
In the age of ¨multitasking¨ it is so easy to shift from one application window to the other, go to a social networking, check email, chat on the instant messaging, send sms to friends.
And we feel we are busy. When in fact at the end of the day very little is done - worse, many small things are done but we let the big tasks untouched, procrastinating it (it is so much easier to reply to email than to finalize a thesis, isn't it?)
Insights about focus are welcome in this thread.
