You can only do what you can do. It's a waste of energy and time to do anything other than what you are assigned to do or is within your capacity. Your career won't progress any faster, you'll just burn through your resources.
Sometimes we have to hit rock bottom to reach our goals in life.
ANYONE can become talented at something, it just takes showing up and trying. You won't know anything about a subject, but if you study for 15 minutes, you will most definitely know more than you did.
