RN, MSN, tobacco treatment specialist, Northwestern Memorial

"I tell people to learn from the past and rather than feeling like a failure-those were practice sessions. Now do what's best for yourself in the present. Rather than thinking changing is something I have to do, look at it as something I choose to do. One of my patients said 'it's the power to let go of what feels familiar.' So take it a step at a time. It's feeling guilty that stops people from making a change."
