Self-promotion is a very strange thing. The idea that you must make a commercial of yourself so that someone you've never met might give you approval is a bit alienating. How do you navigate this? What are you really all about? Who are you even? These are the types of questions you must confront when writing a cover letter, and I can help you out. Don't get the wrong idea though! I'm not going to tell you how to write a successful cover letter, but what I will do is tell you how not to write one. After all, knowing what not to do is how you reverse engineer your way to success.
Here are some excerpts from different cover letters I have written over the years. Most of these seemed like great ways to introduce myself to a hiring manager, but now I understand my follies in retrospect.
In a cover letter you're supposed to highlight your accomplishments, and it is okay to embellish a little just don't do what I did and overstep the embellishment threshold into what may or may not be an outright lie (it's a bit of a grey area, really)
You can't teach honesty, and companies like intangibles. Unfortunately, being honest about mild interest isn't what your second choice, ahem, dream employer is looking for.
It is a good idea to share personal interest with your potential employer, if only to establish a more human, personable side. Just make sure that you don't list an interest that is widely considered awful and pointless.
If I've learned anything in my 72 years on this earth it's that sex and religion make people uncomfortable, so I would suggest you focus in on only one of those things.
This is apparently racist.
This sentence is a bit cocky considering it seems to imply that you've all but wrapped up the job; I would not recommend you include it. The leather jumpsuit however, is a fashion must.
Another thing I've learned is that commitment is an attribute that society is fickle about. Sometimes commitment is an admirable quality and then sometimes you're not allowed to go to high school football games anymore, or follow your ex-wife to her boyfriend's house.
Employers love numbers, so include them as much as you can. I actually don't have any regrets about this particular excerpt.
This one hurts too much to comment on.
But seriously though
