The day has finally come: you're leaving the classroom and are headed into the office for your very first real job. It might be hard to believe, and even a little terrifying, but with the right attitude and a few helpful hints, your first day is likely to be the start of an exciting new chapter.

Look the part

Maybe you're working in a busy downtown office or perhaps you're in a laboratory surrounded by test tubes and beakers. Either way, it's important to look the part and take care with your appearance. It may seem obvious, but wearing inappropriate outfits or arriving with serious bed head sends the message that you don't take your job or place of employment seriously.

These days most employers are business casual which means you don't have to wear a suit, but shouldn't be in your favourite wolf sweater either. Steer clear of any clothes that expose your midriff, bust, behind, or too much leg, and if your clothing is sheer, ensure that you wear a shirt or camisole beneath it. Tight clothing, the kind that outlines every nook and cranny, and ripped, stained, or wrinkled clothes should all be avoided.

In a Huffington Post article, psychologist Vivian Diller says that while most of us would like to believe it's only what's on the inside that counts, scientific evidence, as well as common sense, tells us that an appealing appearance, good health, and hygiene positively impacts our lives.

It makes sense. If you feel confident about your appearance, it's more likely to make you feel confident in other areas like conversing with co-workers, including your boss. So set that alarm half an hour earlier and give yourself enough time to brush your teeth and iron that shirt.

Be professional

Starting new jobs is scary business regardless of whether or not it's your first. It's important to be friendly, polite and to become acquainted with your colleagues, but remember that you're there to do a job, and likely in an environment with people from all different backgrounds. Leave the weekend recaps for lunch or after hours, and keep in mind that not all people share your sense of humour.

With that said, make eye contact and smile, smile, smile. You don't have to be Mr. Rogers, but giving co-workers a simple nod and smile in the hallway helps to make them feel comfortable in your presence and break through any awkwardness. It's also been scientifically proven that smiling boosts your mood, which in turn can improve how you view yourself and others.

Ask Questions

You're new and that means you're not going to know how to do everything. Employers know that, so don't beat yourself up for not being as quick as your cubicle neighbour who's been with the company for six years. Learning is part of the employment process; accepting that you are going to make mistakes and grow from them will relieve some pressure.

Ask your manager whether they prefer to be contacted in person, via phone, or via email if you have questions. That way, when questions do arise, you can contact them directly and not worry that they're wishing you weren't showing up at their desk. Be polite and receptive to their instructions, and if you have a suggestion or question about what they're asking, keep a positive attitude.

Team members or co-workers can be great resources too and are likely eager to help you out. Remember that they were also once new employees and can relate to the discomfort and stress of starting a new job.  

You're there because they know you can do it

Hiring can be a lengthy and intensive process, and these days most jobs have multiple applicants. You were hired because your employer believes in your abilities and that you can succeed at your role. They simply wouldn't have hired you otherwise'it's just business.

They know you're going to take some time to settle in, they know you'll make mistakes, but they also know that you can do it. And if they have faith, so should you!

Go forth and know that you're going to do well. Oh, and don't forget to smile.
