Biggest fear and way to overcome it. . .

As a student of CA, it can be stated that Icai tests us to our extreme before handing us the prestigious degree. We know that some of the students are good with numericals while others can easily deal with theories. And some people are average in both theory and numericals. In one way or the other, ICAI sets a challenge for each one of us with the biggest fears that we may have. Please share, which subjects were/are your biggest fears and how you overcomed/plan to overcome those fears.
