Stumbled upon a video that follows David Cameron around for a day (12 mins).
There are always important decisions to be made. David Cameron sets apart two hours of silent work every morning to not only read up on all kinds of different topics, but also (and this is the most important part) think them through to form his opinion. He does not have time to decide during meetings, as he runs from one to another.
While our meetings (and our lives, for that matter) are probably not on the same level as David Cameron, chances are you have lots of different things on your plate. We can learn from Cameron by setting apart some time each morning to rethink our schedule, what we want to achieve and really be prepared to make those important decisions.
