I’ve spent a good portion of my life serving individuals with chronic illness and witnessing them thrive in the face of adversity. My chronic illness track pulls from everything I’ve learned from patients, military service, leaders in medicine and positive psychology, and my personal journey. Chronic illness does not define you— live your best life in spite of it.
The Happify sleep track is a focused, short-term program that makes state-of-the-art science on better sleep easily accessible. The recommendations should be helpful for people across the spectrum of sleep problems, from those who only experience mild impairment in attention or mood to those with quite significant sleep problems who might otherwise require more intense medical intervention.
Through my Happify tracks, I aim to help employees learn the critical inner skills they need to flourish no matter what (or who) the challenge may be.
Since findings from Positive Psychology have revealed that all success in life is preceded by emotional flourishing, I wanted to create tracks that together did two things that have been found to contribute to a meaningful, fulfilling life: setting and pursuing goals from an evidence-based perspective, and cultivating the character strengths that contribute to becoming authentically gritty.
I am sure that anyone coping with PTSD will now have a much more robust hope of being able to enjoy everyday life more fully after completing our Happify track.
Happify crafted my meditation track on the site with a rare combination of depth and a wonderful instinct for creativity, communication skill, and fun. All too often meditation offerings are authentic but ponderous, or inventive but shallow. I felt that happify got it just right, in a very unusual way, so that participants find the program both comprehensive and accessible.
In my work coaching and teaching the skills of resilience, optimism, and positive psychology, I've been continually impressed by the inherent strength of the human spirit. With Happify I've been able to share many of the science-backed skills I've seen people use to grow through adversity and create lives rich in connection and purpose.
