Employers don't consider your resume follow-up a waste of their time. While there will always be potential employers who are firm believers in the "don't call us, we'll call you" approach, most recruiters admire candidates who make an ef fort to follow up on their resumes. Follow-up shows both initiative and persistence, traits good managers love, especially in individuals who are applying for positions with major responsibilities. Don't worry about seeming too enthusiastic. Company representatives enjoy being pursued. It massages their egos and reminds them their company is worth courting.

To succeed in life in today's world, you must have the will and tenacity to finish the job.

Michael Jordan and Tiger Woods are really part of a very big advertising program, and the fact that they make so much money is because the markets have dictated that they get that money, and the fact that they endorse our products allows us to sell more products and create more jobs.
