I agree with Network 7 about S.

My thoughts are you probably have a lot more potential than you realize.

S is not going to help you cultivate you talents. 9 times out of 10, bosses who are like that see you more as a threat or think too much of themselves to extend a professional helping hand.

I have had bosses in past like S. His opinion of your worth means nothing.

It is your own opinion of your worth that counts.

Work hard and strive to be the best in what you love to do. You will never fail and your opportunities will come because not every boss will be like S.
