Your relationship with your employer is no different than any other business relationship. You can do the bare minimum, just as there are many businesses that do the bare minimum toward their customers, and those businesses often have a low subsistence level of success; if you do the same, you may have the same level of success in your career.

An employment relationship can offer a lot of things for both sides. For the employer, your labor of course. For the employee, a salary of course. But it can also offer experience, access to other talented and intelligent individuals and access to capital to learn and try things, networking, relationships, opportunities for promotion and perhaps opportunities to find better employment elsewhere, or the skills and/or connections to start your own business.

Your attitude toward work should be the same as the attitude you take towards the rest of your life. You can "rot" or you can make the most of every opportunity.
