You cultivate a heightend (higher) awareness for the circumstances you are experiencing...

You push yourself to think/perceive about the circumstances in new ways that weren't previously considered and entertained...

You find yourself reaching a point where you are so fed up with operating a certain way and with thinking/perceiving in a certain manner - that you are finally able to push/steer yourself in a new direction and explore previously uncharted 'territory'...

You can also ask your self questions which stimulate deeper contemplation and which will eventually yield new insights and again, promote a heightened awareness for what you're experiencing... Like asking yourself if your current manner of thinking/perceiving is doing anything to contribute to your health and well-being? If the answer is a resounding NO - then continue to contemplate and evaluate your relationship with those thoughts and perceptions, and why you would seek to maintain your attachment to them... Such a conscious exercise/practice does not yield immediate changes/results - however it will importantly and necessarily influence you to start breaking down the attachment to and identification with your former limiting ways of thinking/perceiving (which were not serving your highest interests)...

I heard a quote not long ago that went something along the lines of:

"You can't solve problems with the same level of consciousness that created them"
