I should apply to as many companies as possible - myth

Printing off multiple copies of your CV and mailing it to every address you can find may appear to be a logical step: but it isn't. Whilst companies are often very interested to hear from motivated people like yourself, they are especially interested in people who want to work for their organisation in particular. Send fewer applications, but make each one a good one. Make it look like you really want to work for that company and explain how you would be of value to them. When it comes to making applications, perseverance is essential but quality really is better than quantity.
