"Chance favors the prepared mind."
– Louis Pasteur
You are most likely to succeed in life if you use your talents to their fullest extent. Similarly, you'll suffer fewer problems if you know what your weaknesses are, and if you manage these weaknesses so that they don't matter in the work you do.
So how you go about identifying these strengths and weaknesses, and analyzing the opportunities and threats that flow from them? SWOT Analysis is a useful technique that helps you do this.
What makes SWOT especially powerful is that, with a little thought, it can help you uncover opportunities that you would not otherwise have spotted. And by understanding your weaknesses, you can manage and eliminate threats that might otherwise hurt your ability to move forward.
If you look at yourself using the SWOT framework, you can start to separate yourself from your peers, and further develop the specialized talents and abilities you need to advance your career.
