Staying on Track

As I have come closer to the awareness of my true nature, something  has always come up to stop me from moving forward. I become attached and clinging until I no longer can take the pain and suffering I have caused myself. Starting over, I am relieved but find I have this habitual way of being which does not allow me to progress very far. Inevitably, I will experience some discomfort which will force me into non-action toward self-realization. How can I stay on track?
