Whenever we are sad, we get introduced to our limitations. It become easy to overcome your limitations when you know them. This way you can leave behind your limitations and focus only on your strengths.
Our lecturer was teaching us the limitations of one of the management concepts (Human Resource Management, if you are too keen to know) in India. After that she asked what can be done to overcome these limitations. I thought it was very easy to answer this. I started to read each limitation one by one and then went on to explain what can be done to overcome that limitation. I think it would be very difficult, if I didn’t knew what was the limitations.
See if this work for you, write down your limitations (like fear or short temper) and suggest way to overcome these. It has been helpful to me, maybe it can help you too.
