Unfortunately the most effective method is to "just do it". Once I've overcome the inertia to start the ball rolling it usually gets easier. The act of doing often leads to ideas of more interesting ways of achieving the goal of the activity. Or a realisation that I would be better off abandoning the activity altogether.
