I find focus in strategy - the art and science of planning and marshaling resources to achieve your goals. First you start with your goal, then you assess the various strategies that will support that goal and identify the tactics that you will implement to execute your strategies and map out how you will measure each tactic's success. It may sound simple, most good strategies do. I keep my goals, strategies, tactics and metrics front and center in everything I do.

Here is a simple example:
Goal: Build My Brand
Strategy 1: Connect With Others
Strategy 2: Storytelling
Tactics: Being active on LinkedIn, Attending Local Events, Blogging
Metrics: LinkedIn Stats, Conversations and Connections, Social Sharing of Content
