What you focus on expands, so aim your lens towards the positivity you seek, and watch how it shapes the picture of your life.

This metaphor compares life to using a camera. It suggests that in life, one should concentrate on what truly matters, cherish the positive moments, learn from the challenging ones (the negatives), and if circumstances don't go as planned, try again just like taking another shot with a camera.

The phrase "What you focus on expands" implies that where you direct your attention or energy tends to grow or become more prominent in your life. Therefore, the advice is to focus on the positive aspects you desire because that focus influences and shapes the overall quality and direction of your life.
