Writing: Clear & Precise
The education system is designed to completely shake you off. Forget about improving skills, it even nullifies them.
One example point that I’ve recently experienced:
In school, you were forced to write long essays to get more marks. Over time, this habit gets compounded, and we developed the habit of writing lengthy and redundant sentences. And it is completely opposite what people expect in the real world. The more precise and clear you can write, the better you’re.
