When I was about 17 I read Being Peace by Thich Nhat Hahn and Be Here Now by Ram Dass. These books were exactly the sustenance I craved to make sense of my confusing teenage existence. I am thankful that they led me to yoga, meditation and mindfulness, and shifted my world view at a young age.
When your unhealthy habits are insignificant in comparison to your deep desire to be mentally, spiritually and physically healthy, I believe you are practicing mindfulness. It is a knowing that you are worthy of a heathy lifestyle and in believing so, you understand that practicing meditation, yoga and healthy eating is required on a daily basis.
There is a time for everything: a time to work, a time to play, a time to reflect, and a time to just breathe. There is always perspective and reminders about what is important even amidst daily challenges or in times of deeper turmoil.
My career of nearly 40 years as a graphic designer and creative manager was always highly stressful, with many tight deadlines and the pressure to be creative on the fly. At times, it was very exciting, and I loved the challenges.
