When you make the transition from working in retail to working in an office, your new job will be unfamiliar and even a little scary. It can be hard to know what to do and how to act; I know it was for me. However, since entering the professional environment myself, I've picked up on some little tips that can make all the difference when it comes to being successful in the professional world.

1. Invest in your wardrobe.

Whether you're a man or a woman, you really need to have plenty of business clothing in your wardrobe if you want to be successful in the professional world. It might be unfair, but you really have to look nice to be taken seriously. Having at least one good suit is essential, and you should have enough different shirts and accessories to avoid looking like you're wearing the same thing all the time. If you don't want to spent a ton of money, try shopping for professional clothes at outlet stores such as Ross and TJ Maxx or go to a bargain department store like JC Penney. Say good-bye to jeans and t-shirts; it's time to dress up.

2. Speak up.

You might be the new employee or even just an intern, but don't be scared to speak up if you have some insight to add to a discussion or a new idea you want to try out. That doesn't mean you should speak without thinking, but you shouldn't stand as silent to a stone. In the professional world, initiative and boldness are appreciated. Be sure to bring what you have to offer to the table.

3. Go in early and stay late.

It's true that this isn't an option for everyone, but if you can, you should try to go into work early and stay late. You don't have to stay for hours of extra time, but it's helpful to arrive at least ten minutes earlier than you need to and leave about ten minutes later. However, make sure you are actually getting work done and going the extra mile with those extra minutes— it won't look good to just be sitting there twiddling your thumbs. If you use this tip, your boss will notice and appreciate the dedication you have to your job.

4. Say yes to social events.

Networking is important, especially during the early stages of your career. If your coworkers invite you to have lunch with them, join them. If your boss invites you to an after-hours reception or dinner, try to go if you're available. You want to become known in your professional circle. It's always helpful to put your best foot forward and ensure that when you're name comes up, your peers have a name and personality to match to it.

5. Walk quickly.

This is a minor tip that was given to me by my first boss. You should try to walk quickly through the office so it looks like you are doing something important. Avoid looking like you are lounging around or not in a hurry to get back to work. It may seem like a silly tip, but it's the minor details that can make all the difference.

6. Check your work e-mail from home.

Checking your e-mail from home is a practice that is greatly beneficial but only takes a few minutes. You don't have to take on large action items when you're out of the office, but if you spare a moment to answer a quick question or approve a final copy of a report, your colleagues will definitely appreciate it.

These small adjustments will definitely help secure your success in the professional world. Good luck out there!
