The strengths that have come naturally to you are the first ones to be nurtured by you in the order of priority. What you can develop on top of that helps you further in placing yourself apart from others. Nurturing the existing strengths and developing the new ones are two continuous processes that shall run in parallel.
Be aware of your limitations and weaknesses. Don't worry much about the former and work as much as you can on the later. But, concentrate on your strengths in a greater extent. Go for it and win it.
