I’m reading a book right now titled The Clean Coder. Here’s a quote from chapter 1:
Your career is your responsibility. It is not your employer’s responsibility to make sure you are marketable. It is not your employer’s responsibility to train you, or to send you to conferences, or to buy you books. These things are your responsibility. Woe to the software engineer who entrusts his career to his employer.
-Robert C. Martin, The Clean Coder
