A path is made by walking it. This is about recognizing life takes on the meaning it is given. Its easy to be positive or optimistic yet being overly positive doesn't allow feeling deeply. In fact, it blocks out shadows or another side of who we are. We are often taught to rush through adversity to avoid pain. This does not allow us to get through pain or allow feelings entirely appropriate for different situations. Is it always desirable to rush turning a frown upside down?
A true Yoga perspective would say no. Each person's truth ought to be honoured. All feelings in the moment deserve love and acceptance. Healthy emotional stages allow for shock, anger, disappointment, sadness then acceptance and reorientation to a more balanced focus. Eventually, its useful to be more fully open to the unknown or new possibilities. To allow everything to flow, and seeing this is part of wholeness, this is truly walking the path. The truth is only ever felt directly.
