I believe everyone should try to be strong at logic and have good reading habit. Because If you possess these two skills, no matter what difficult situation is, you will definitely find a perfect solution out of it. While logical ability gives you to understand complex problems and concepts quite easily, reading habit gives you an open mind and holistic approach to see much bigger picture.
