Many of our threats are imaginary. The habits and even obsessions that we develop to keep them away are destructive and undermine our moods constantly.

Almost all negative moods are missing one key element - calm. By learning calm, you learn to deal with difficult areas. Calm allows us to achieve what we want, without being overwhelmed by anxiety.

Many physical illnesses are associated with depression and anxiety, including heart disease, high blood pressure, diabetes, Parkinson's disease, stroke, kidney disease, lung disease, dementia and cancer.

All moods have a cause. If you change the root cause, then your mood will follow suit. Furthermore, mood is a choice. It may not be a completely free choice, but you can choose which mood you spend the most time in.

Postural exercises such as yoga, Pilates, Egoscues, Alexander technique and martial arts are about avoiding pain and injury as much as helping you feel good. Attractive men and women have good posture.

Even a simple imaginary exercise can change your mood: Close your eyes, and take yourself back to your last holiday where there was a lovely warm sun, beautiful sea, relaxed beach and fun meals in the evenings. Open your eyes and consider how you feel now.

Beautiful and familiar objects can help us to feel better. Photos of family and friends, which remind us of the people we love and who love us, are important mood-lifters. Items that inspire us or encourage periods of reflection do the same.
