Do you have a personal improvement goal that has proven resistant to your sincerest intentions, smartest plans, and best efforts? If so, then this course is for you. Last spring, we kicked off a world-wide experiment to see if Kegan and Lahey’s ground-breaking, award-winning approach (the Immunity to Change process) could be deployed online to help tens of thousands of people make lasting changes at work or in their private lives. The experiment was largely a success! Many participants succeeded at making important changes in their lives. Here’s what our students have to say:

• “When I first started, I was a bit skeptical on how I would actually change. Looking back at myself 14 weeks ago and comparing it with how I am now is incredible! I couldn't be happier that I decided to take this course and learn a new approach to change. My life is so much better because of it.”
• “Someone asked me recently if I felt like I'd just wasted 14 whole weeks on self-inquiry. I can honestly say no - I feel like I wasted 30 years sleepwalking!  An incredible experience. Bob and Lisa have created a truly wondrous process, and the staff and fellow students have built a rich and supportive learning environment.” 
• “I appreciated the opportunity to feel like I was a part of a bigger community striving to grow and improve. This made me want to constantly push myself because I believed in the power behind the material and in the power of being part of a community working toward similar goals.”
• “This has been an amazing course and I have made long lasting changes that I didn't even dream about when I began this course. There is no way to express my deepest thank you for that . . . my life is changed.”
