Invest Some Time Each Day in It
There are many justifications for not doing BD: I was too busy on a client matter, I had to run to court, the meeting went over schedule, and the list goes on and on. There is always another thing, always something else that is demanding your attention and focus. You have to prioritise profile and practice growth if you want to succeed, and a good place to start is by allotting a small amount of time each day to concentrate on your BD efforts.
Before you get caught up in the daily craziness, mornings usually work best. Schedule this time in your calendar, shut the door, and avoid interruptions. Your essential BD moment is now.
