Can you create value if you are constantly in fear of making a mistake? I think that you must push the envelope at all times in order to keep creating value and staying ahead of the competition. Mistakes occur from time to time, and I think that is perfectly ok as long as you learn something and move forward.
Are you stuck in a position where you constantly fear screwing up for fear of losing your job? You will never learn anything new this way, and you will only get better at the systematic process you are stuck in and relied upon to deliver everyday. Don’t become irreplaceable or you will never break free of the role. Find a position where you can constantly innovate and create value – push the envelope, make some mistakes, and move forward.
