EmploymentCrossing CEO, A. Harrison Barnes, discusses the importance of not being persuaded by others regarding the way you carry out your job search:
When you are looking for a job, as with most things in life, you know better than anyone else what works for you. You should not let other people tell you not to try some method just because they don’t personally like it, or because they think another method is better for some reason or another. While someone else’s method may be great, you should not follow it and ignore other options. Instead, the most prudent and most productive path to take is to heed others' advice and try other methods, but don’t stop doing something or never try something just because another method works better for someone else.
What it boils down to is that you need to be inclusive, rather than exclusive. You need to work every angle and try every method you can think of in order to carry out a successful job search. Do not foreclose on potential opportunities by letting other people convince you not to try everything possible to get the job you want.
