Since some changes are more difficult than others, like dietary adjustments and adding new activities, it s important to consider and accept the possibility of you experiencing happiness with these changes. Fully accept the possibility that you can be happy with other things that could take the place of, for example, a favorite food item or activity that would be prudent from which to refrain. It would be a time of great acceptance of many things. After acceptance, if an open, positive attitude is practiced or cultivated, comfort and serenity can be experienced. Your results are often in direct proportion to your efforts.
Disciplined practice is what it takes for many to achieve certain skills.
Having an open and positive mind is something that many people have to regularly practice, like a physical activity, to achieve. I would also make other lifestyle changes as well. Herbalism works better within a holistic approach to health. An illness is then thought of in terms of the whole person, not just an organ or area in the body. I would read many books on holistic health.
