When you're creating profiles on social media sites like LinkedIn, Twitter and Google+ it's important to add a photo to your profiles.  If I'm making a decision on whether to connect with someone, I always hesitate if there's no photo.

Adding a photo will enhance your professional image and will let those networking connections who you don't get to meet in person connect a face to a name.

When you're using sites for professional and career networking, nobody wants to see a blank avatar where your photo should be. And your picture should be a photo, not a cartoon, a random graphic you happen to like, or a cute image of your kids or dogs or anything else. Your photo should be a headshot and should be appropriate for professional connections to view.

It's also a good idea to be consistent across all your online profiles, if you use the same themes and photos you will be able to create a strong personal - and professional - brand.

Here's more on how to add a photo to your LinkedIn profile and some examples of online profiles.

Who should you address a cover letter to when no contact name is listed in a job posting?

If the contact person is unknown, and many employers deliberately don't include a name when they advertise jobs because they don't want applicants contacting the hiring manager, you can use a general saluation or leave off the salutation from your cover letter and start with the first paragraph of your letter.

There are a variety of cover letter salutations you can use to address your letter. Employers who responded to a recent employer survey conducted by Saddleback College preferred:

• Dear Hiring Manager (40%)
• To whom it may concern (27%)
• Dear Sir/Madam (17%)
• Dear Human Resources Director (6%)
• Leave it blank (8%)

Here's more information on how to address a cover letter when you don't have a name to include or when you're not sure of the hiring manager's gender.

Taking a career test is a little like playing "what do you want to be when you grow up?" with a twist.

It's also fun to see the options for your future.

What do you think? Do you have ideas about what you might want to be when you grow up? And even if you are grownup already, it's never to late to think about what you want to do next in your career.  In fact, I just saw an AARP commercial focused on what you want to do when you grow up!

Here's advice on deciding what you want to be when you grow up, along with tips on when and how to decide about career options.
