*Career Services Office. Your Office of Career Development can be a good source of benchmarks.
*Student Coach. If you can find one of my many former or current students, ask him/her to coach you. No kidding; (s)he’ll get a lot out of it, and there’s a good chance you’ll get specific, practical, valuable help.
