I did a lot of puzzle in these months, my puzzle rating goes up to 2700 this month.
The most obvious change made in my job duties is that I did my job more carefully.
I used to be a careless person, I've been making a lot of mistakes in my work.
I used the puzzles in chess.com here to make me a careful person.
I have to be concentrate, slow down and think about more 'before and after' when I am solving the puzzle, and I bring it to my job and succeefully make it better.
