How to write personal shortcomings how to write personal shortcomings

Personal shortcomings can be written like this:

Everyone has his own advantages and disadvantages, and of course, I am no exception. Let me talk about my shortcomings first.

My first weakness is timidity and lack of self-confidence. In class, the teacher asked me to answer questions, but I was always too timid to speak. When the teacher tells me what to do, I always push from pillar to post with confidence. When I stay in a crowded place, I sometimes feel scared.

My second weakness is procrastination. I am a slow-witted person. No matter how anxious others are, I always take my time. Every time my mother asks me to do housework, I always put it off again and again, and finally my mother is worried.
