In the first section of the reading the book it explains how to learn to say “No”. Sometimes you’ll work with managers or clients that expect too much from you, it is not professional of them to ask you to do more than you can. If you know a workload is going to be too much for you to handle do not hesitate to say no. To be a professional you must know when to say no to a client. The client is trusting you and your expertise, so do not agree to something you can’t do just because they are paying you.
In the next section talks about not rushing during coding. If you rush during coding chances are the quality will depreciate. If the quality is not up to standards then the code will be extremely hard to change later on. So the best way to code is to take your time if you want your software to be able to be maintained in the future.
