Having been trained on 7 habits for highly effective people about one month ago. These 7 habits can only be applied if we succeed to apply the first habit and go on to the next habit. If we cannot apply the first habit then we cannot go on to the second habit and so on. The most basic habit is be proactive. Proactive is more than having initiative. Be proactive means take responsibility on our attitude (in the past, present and future), and can make a choice based on principles rather than our mood or feeling or condition.
Based on the definition above, being angry, stress, happy or sad is a choice. We determine our circumstance. I think this principle is really true indeed. However, somehow it is really difficult to be applied. What do you think ?
