Kaizen (改善?), Japanese for "improvement" or "change for the best", refers to philosophy or practices that focus upon continuous improvement.
No one wakes up a completely changed person. Instead, improvement is made in "baby-steps," and is a lifelong process. One of the focuses in functional medicine is to changing lifestyle habits - which can be a challenge for anyone.
Know that each small bit helps, and rather than view any potential back-steps as failures, see them as learning opportunities to assist in your future improvement!
In the detoxes since, I have made additional small changes one at a time - I stopped smoking (ok, that's a big one,) started regular supplementation and chiropractic care, eliminated processed junk foods, moved to eating only whole foods... you get the idea.
I encourage you to consider this philosophy when facing any challenge that seems overwhelming. What will be the first step in your personal Kaizen?
