Should I include references on my resume?

Yes, if the employer requests them or if you know that the employer like to see them with your application. Otherwise it is a matter of personal choice. If you don't have a lot of work experience but have excellent references who can talk about the quality of your work and they are well respected/influential in your community, then it may work in your favour to include your references. Whether you decide to include them in your resume or not, make sure you have references ready if an employer requests them at an interview.

What can I do to ensure I have a great job interview?

The key is preparation. Research the company to which you are applying. Know what the company is all about and what role you wish to perform within the company. Practice your interviewing skills and rehearse your responses to possible interview questions. Purchase professional looking business clothes and be conservative in your appearance. This means covering up tattoos, removing unnecessary jewelry from piercings and adopt a conventional hairstyle. Employers are more comfortable hiring people who look like they fit within the culture of their company. First impressions count!

I've been job searching for a while now but I'm having no luck. What am I doing wrong?

You may not be doing anything "wrong" but could be doing things more effectively. Start by having a professional look at your resume and provide you with feedback. Does it look professional? Does it do a good job of marketing you to potential employers? Next, how effective is your job search? Are you only responding to job postings? Do you have an organised system of cold calling and follow-ups with local employers? Do you network effectively? What does the local labour market look like for jobs in your career field? What other related jobs have you considered?

I have no idea what I want to do once I graduate from high school. What do I do?

Start with a checklist. Create a list of all the things you enjoy doing and your skill sets. Your interests and skills do not have to be career related! Once you have created a list, cross check which field your interests and skills resonate the most with and opt for that.
