I do my best to please every customer because that is a big part of my job.
Job satisfaction on the other hand is a big factor when it comes to talking about flight instruction. If the instructors can live on their salary from instructing then they are more likely to perform better on their job.
I cannot instruct just for the fun of it. I also have to get paid because pure fun doesn't fill my stomach at the end of the day. Though I have to admit that I do the same as every other low time pilot, that is I take every flight I can and think little about the pay. That is why I have another job, to pay the rent and all that boring stuff. My missus also wants to have something to eat every day.
Happy instructing,
