Pick some long range goals that feel exciting. Pick one of those goals that can be visibly achieved in one year. This is the most important thing you can do. Break down the goal into a timetable and specific tasks, with tasks assigned to a specific person. Evaluate regularly to see how effective you are.
Great achievements start out as little tasks.
Great oaks from little acorns grow. Creating a community vision and plan is important. It is exactly what a business does with its mission statement and business plan. For example, the Dudley Street Neighbourhood Initiative, a community group in Roxbury, MA, USA, got several small but significant victories as they worked to stop illegal trash dumping and to involve young people in community healing. This helped them to 'take over' their neighbourhood.
