I thought that Glencoe’s Career Tips were fairly traditional, but I liked the last point a lot:

Respect Yourself
Remember that the ultimate goal of your job is to satisfy your needs—for money, lifestyle, recognition, accomplishment, and advancement. Keep your career goals in mind and keep working toward them. Be the best employee you can, and some day, you’ll have that career you always dreamed of. Don’t stick with a job if it’s not right for you. If you’re not challenged, find a job that challenges you, and keep working for your career goal.

Amen to that.
