Can a meditation course help me focus?

Focus is trainable, and a course suits it well because attention improves through repetition rather than insight. Focus and clarity is one of the goal areas a course can be built around, and breath focus is the technique aimed most directly at it: you place attention somewhere, notice it has wandered, and bring it back, which is the repetition that does the work. In StillMind you can build a Goal-based course around focus, or a Techniques course centred on breath focus if you would rather learn the skill itself. Sessions can stay short if long ones are hard to sit through.
