I suggest that major administrative responsibilities be left for relatively late in your career unless you decide that this will be your primary focus, in which case you will need additional training in administration. Your early years in any position are very important and I think it’s best not to clutter them with extensive administrative responsibilities, too many committees or generally unproductive time commitments. Accept your fair share but learn to say no. Because of the high prevalence of many diseases in the developing world, involvement in international health might be an attractive option for some of you, but it is preferable to establish yourself at home before taking on the rest of the world.
There are two skills that may not have been emphasized in your training but they will be very important to you in the years to come. The first is the ability to manage your time efficiently – the discipline of presenting the relevant features of a case concisely, of adhering to a schedule and of avoiding endlessly circuitous discussions. In short, learn to make your time count. I suggest that, at the end of the day, you assess what you have achieved, and that you consciously explore strategies to improve your productivity, distinguishing between crucial activities and those that were of peripheral importance or a waste of time!
