What is balance?  It's difficult to say exactly what constitutes a balanced lifestyle, as it means different things to different people.  However, I can indicate signs of imbalance:

• low energy levels
• mood swings
• fatigue
• angry outbursts
• ill health

If you are experiencing one or more of the above, there is definitely work to be done.  All of the above are merely signals from your body suggesting a change of direction. Isn't it funny that, as a society, when we're hungry, we eat; whereas when we are experiencing ill health or extreme emotions, we are less quick to move towards a solution.

I would recommend implementing at least 2 of the following, if not all of them:

• seeing a nutritionist, as you may be lacking in certain nutrients
• meditation (to relax and clear your mind)
• yoga (positive for the mind and the body)
• change in career
• more sleep
• exercise
• spend more time surrounded by nature
• take a holiday/ short break
• give up stimulants (caffeine, alcohol, drugs)
