Disorders, heart attacks, burnout and exhaustion can be scary. Especially if you work long hours and go from one business meeting to another, you may end up feeling exhausted and even desperate.
As difficult as it may be, you need to learn how to take some time away from your current projects. A few breaks and time-outs will lower the risk of burnout. Burnout would put you out of action for at least several months; in comparison with this, time spent resting is definitely not too high a price to pay. If you were to let things go too far, you would ultimately lose much more time.
Many people believe success is somewhere in the future. In reality, if you are following your dreams and taking brave risks, you are gaining a great deal also in the present. With self-care, you will have the time to think about your goals and perhaps realise that you have already achieved something.
