Leaders are fascinated by future. You are a leader if and only if, you are restless for change, impatient for progress and deeply dissatisfied with status quo. Because in your head, you can see a better future. The friction between 'what is' and 'what could be' burns you, stirs you up, propels you. This is leadership.
You grow most in your areas of greatest strength. You will improve the most, be the most creative, be the most inquisitive, and bounce back the fastest in those areas where you have already shown some natural advantage over everyone else your strengths. This doesn't mean you should ignore your weaknesses. It just means you'll grow most where you're already strong.
If you want to be clear, act.
Convey your passion and link your strengths to measurable results. Employers and interviewers love concrete data.
