What is the "right" path?

So many times we get caught up in wondering if we're on the right path. I've come to the conclustion the answer to that question is a simple one:

If the path you're on is moving you forward, not taking you backward or stagnating your progress, then you're on the right path.

Mindfulness

"When the Buddha was asked, 'Sir, what do you and your monks practice?' he replied, 'We sit. We walk, and we eat.' The questioner continued, 'But Sir, everyone sits, walks and eats.' And the Buddha told him, 'When we sit we know we are sitting. When we walk, we know we are walking. When we eat, we know we are eating.' 
Most of the time we are lost in the past, or carried away by future projects and concerns. When we are mindful, touching deeply the present moment, we can see and listen deeply, and the fruits are always understanding, acceptance, love and the desire to relieve suffering and bring joy."
— Thich Nhat Hanh, Living Buddha, Living Christ
